Amateur electrical nooby here. Out of the last 25 videos I've watched on wiring, this one has been the most helpful! Thanks a ton for posting this! 🙏 👍👍

I have no clue about anything auto electrical. I'm starting my own catalogue of writing in a book about this and that and I can say that your video has helped make that list become more understandable. Thank you (I don't care how old the video is)

You had me at “like a hotdog in a hallway”. Reminds me of a girl I once knew.

Great information and techniques. Really appreciate you taking the time to share

I just started working with these Deutsch connectors and I really like them a lot. Even the cheaper aftermarket plugs seem to be miles better than the best weather pack connectors. Like stated in this video, once you have all the tools needed to do the job properly, it's really fast, easy and secure.

Thanks for taking the time to share.

Absolutely fantastic video....tool choices, basics on wires and connectors...awesome...subbed! Looking towards watching more of your vids (#100)

Great wrap up of basic wiring mate, useful info, thanks.

I 100% agree with your comment about wiring issues and Dyno Tuning. One of my favourite sayings is " just a tune" 😁

Thank you for going over this.

Awesome Broomy!!! Stoked to be here.

Thank you for this! It was great.

What a fantastic and informative video. Thank you and greetings from Portugal.

This video is amazing. Deserves so many more views and subs

I was looking for a how to video on automotive wiring to make a better job of the accessories I have fitted to my car i.e. siren and PA. Great video and have subscribed to your channel. Its a pity the focusing go's out a bit trying to see the fine details on some of the techniques you used. Great advice thanks.

Great, informative vid. Thanks for making.

Really straightforward and informative, thanks. You had a bulkhead connector on your table that I was hoping you were going to get to. Which one do you prefer, as I am at the point of wiring my elite 2500 to my Subaru harness.

Very well taught Broomy. I'm an A Grade Electrician with data and security as well as Motor control and process control experience. I must say, for at least 9 out of 10 car builders, the answers you've given are exactly what I'd suggest. The only extras I'd offer are soldering the pins rather than crimping (but only if your soldering skills are good), copious quantities of heat shrink and re-useable cable ties with panel pins to secure to holes in the bodywork. All in all, I'd agree with you about people overcomplicating wiring for no real benefit. A further benefit of your recommendation for the Deutsch plugs is higher surface contact area reliability between the male and female during the plugging process.

Excellent content

Gold info Cheers

Informative 👍🏽

Thanks sir lesson

Great information, thanks 👍🙏

Holy hell this video was great! Thank you for sharing.

“Like a hotdog down a hallway!!” 😂😂😂 great video by the way

Thanks for making this video. Its a little less scary now

Awesome video !

Royt Mate, Thanks for the vid. Interesting shop you have there, All metal construction ?

Thanks sir

How much do you lose in length for the reduction in diameter? Looks super clean either way!

Great video. We must work on the same kind of stuff, high performance engines, standalones, etc. I agree with everything you said, except one point I don’t especially like about the Deutsch terminals versus some open barrel style crimp terminals is that they don’t offer the strain relief where the crimp portion of the terminal has two discrete areas it crimps. The first actually crimping onto the insulation and second crimping the just the conductor. Are you familiar with Molex brand mx150 connectors? They are a proper connector with rubber seals on both ends of the connector, a nice audible snap upon connection, have range of 1-20 wires, and even have two or maybe even three different terminals for different gauge wires so 1 connector can work for various gauge wire. They even have slots where you can slide in mounting tabs for those Christmas tree looking push in a hole deal to secure wires from sagging or whatever. About the same price for the most part. If you’ve ever worked on a later model Harley you’ve encountered them on the handlebar controls and under the fairing for almost everything. But yeah, the dt/dtm/dtp from Deutsch are great for almost everything. I use them for 80% of what I do. Anyway, have a good one and I’m bout to subscribe and check out your other videos!👍🏻

Good video . You should give the product description of the wire you are I using in the description. Another thing too is that the cheap Deutsche connectors are flimsy and flex . Pull apart too easily .

great stuff, as I am torn on my mgb. So anderson connectors no go?

i work with a well known custom canopy and service body manufacturer. i do wiring on daily basis for Utes.We never rely on clips. We do solder as it is most reliable method. I use long noze plier instead of side cutter.even fro 5 cores , 7 cores wires. the stripper has clips features too. i use them whenever required. so basically plier, stipper and a solder are enough for wiring. soldering tool is good investment instead of clips. for DIY i suggest also add tester screw driver. it will save ur time on finding wires and issues, blown fuses etc. .

dont quote me, but im sure wire current capacity is not measured by measuring the outside jacket. I believe its done by measuring 1 stand, then multiplying it by how ever many are in the bundle to get an overall diameter

Hey, good day. What size wire would you recommend for power and ground for IGN1A coils ?

This is one of the better videos out there. The fact that you use Deutsch Connectors is awesome. Quick question though...what's a solid way of tapping into an existing wire?

I get your complaints with the fastin faston connectors (the generic white ones) but you can get the right size crimps for thinner (or thicker) cabling. If you're using the right size crimps and crimpers they're perfectly fine.

Having a twist in the wire helps with RFI. The magnetic field cancels..(srs systems)

Its kinda fun to look at the reasonings why things are done as they are from the common folks perspective. I am a assembler who has built and in part designed large automation panels to small wire harnesses for vehicles to semicon industry. Twisting can be done to safe space. Usually its done to analog controls to make the magical magnisation stuff less fucky. The common flat connectors contacts are available in smaller sizes. Deutch connectors are good because of their environmental properties and superior crimp contacts and good built quality. -one scuffed tip is to strip the wire longer and fold the copper. NOT RECOMMENDED! but better than just crimping small wire to too larger contact. Thick insulation in wires is for better voltage/heat resistance and harsh environments. Cauge is just stupid american standard for conductor size, but almost all crimpable contacts use that so you have to deal with that. 11:55 the crimp you made is faulty. The holes in the contact are for inspection. You should see copper from that hole to make sure the wire is deep enough 14:50 and that's the built quality but the contacts wont be that loose. The contacts inself will suppourt each other, but its better that the contact housing takes the movement stress rather than the contacts in them selfs that's why you should use deutch or similar in vibrating and moving applications. Im too drunk to commantate furher frogive me and skip this comment thanks and bye.

Do you need insertion and extraction tools to fit and remove pins from the deutsch connectors?

I’m restoring a 1980 Camaro. I’m wanting to replace my wire for my engine bay. Is there a special wire to use in an engine bay?

We working in it bro..In NEW FLYER cables and wire harness division

for LED shall I use 12 awg? Shall connect tow led on relay one switch?

i just want say THANKS

I recently fitted a new wiring loom in my car, and it came with those cheaper connectors, which I thought were good. Now I know better. I originally wanted to watch a video on extending the wiring to make it neater, but I've watched this and learnt a lot more. Cheers.

Can I rewire a 4pin to a 3 pin even though the wires are a different color from each other. For example running a 4pin pigtail connector wire fuel line to a 3pin pigtail connector wire harness that connects to alternator and distributor?

I have a 97 mustang, when it's cold outside and I start it up the wipers come for a cycle. any idea what could fix that? everything else is great.

Those are some great tips on wiring! Thank you! Do you have links to purchase the tools you were displaying and using?

The white generic ones comes in multiple sizes too, tbf. The white ones are used as OEM on bikes and cars for a reason, its called "good enough", and weather sealed connectors are not always worth using. That said, i like both options. Also a tip for the twisting of cables, when you are finished twisting if you apply heat with a heatgun on the loom, it would often not loosen too much when releasing from the chuck of the drill.

Great video! Are the 3 different sized red handled pig tail crimpers available through any auto parts store? Where/ how did you get yours?

How latter on when you'll have to disconnect all the plugs again, you wouldn't mess them up? In OEM wiring all your connectors are different size, and it's barelly possible to mix them. While having just 3 different one.. that might bring some trouble when putting things back again.

hi can i use jumper lead cable to run from battery to switch panel in boat using a 30 amp breaker i cant afford to pay $30 a meter for each plus and neg lead

What do you recommend for bulkhead connectors? Vid very helpful. Thanks

A quick tip you can double up the wire (conductor) size by stripping it twice the length and folding. Not recommended for everything but those cheap male and female push on crimps wouldn’t just pull out.

Welcome to any wiring elite nerds snobs who are having a screeching fit at their phone after seeing wires being twisted in a drill. Sit down and dry your eyes mate, and take comfort in knowing you’re still superior to rest of us ;) you can purchase the plugs and tools used in this video here mrpartscomau.myshopify.com/collections/electrical-connectors

Great video where can I get that thinner wire from?

can you back probe D connectors for diagnostic testing....seems like it would be hard

If the wire is too small for the crimp-connector to grip it properly, either solder the wire to the connector, or double the stripped wire back on itself to form a thicker crimping-wad for the connector's crimp-surfaces to grip onto.

meanwhile; 10 other channels tell you to solder :-) twist and tape is the best, love that adhesive ingress between the strands

For greater security at any wire crimp; strip extra insulation and fold over the end. It has to ball up if it slides and will not let go. I have done this for 40 years and never seen one pull out.

I'm about to have a crack at rewiring my 70s Aussie muscle car which have a pretty basic harness in them. Do you recommend any particular brand of wire that is good quality and on the thinner side as mentioned in your video.

Great video mate, wiring nerds have a place too, no doubt you seen the shit people do out in the field, ive seen so called pros use normal pliers to crimp connectors and tell you she will be right. love the drill technique, not much difference to how they are twisted in a factory, as long as your not putting mechanical pressure on the copper your fine.

Im new to wiring and stuff. Im installing 3 led kits all 12v. Gonna be using a 12 gauge wiring and hooking all of the kits to the single wiring into a 20 amp fuse tap. I did research and i shouldnt have to worry about my wire being too long right? Should I use a relay? Also cant i just connect all of my ground wire from my 3 led kits to the same ground wire or do they have to be separate for some reason?

Here's another video deserving of two likes!

If you dont know which size of wire the right one is for the device, just use the thicker one. Use this cable for your whole project, the price really makes not much difference but you are on the safe side. And why twist? It makes all stiffer to go around corners like through the door hinges

I have a 1980 Camaro v8 and I’m needing to fix some wires that a mouse chewed up. What gauge would be best for turn signals? Also is there a special automotive wire I need to get?

Question related to vehicle wiring. I have several older Aprilia 125s. On these there are multiple places where a number of wires are joined. One example is in the short section of loom from the clocks. In this the ~12 earth wires (from each bulb, etc) are joined down to a single earth terminal on the connector, with a series of 2~3 > 1 joins. Second example is in the middle of the main loom there is a point where ~8 wires are joined together (these wires are the switched live) in a single join. Both these use U shaped crimped butt connectors. Both are prone to failure. What is the best way to do these kind of joins? On one bike I rewired it and used heat shrink solder butt connectors, to join multples into one (I added an extra layer of heat shrink to further support the joins, and these joins are within the main heat shrunk protected loom). Looking online I have been unable to find an "approved" way of doing such joins.

Why not solder the crimp afterwards for the cheap ones?

Hey mate. Where are you buying all your stuff. Not ya typical Repco parts.

I'm glad somebody finally come out with a better way instead of doing it the half ass way.

couldn't agree anymore with the garbage connectors and type of wire to use. attempted a wiring harness repair on my audi and those connectors would come off the wire with the tiniest amount of pressure!

Just a suggestion… When you’re shooting close-ups of the components you’re demonstrating do it in front of a solid color background without any high contrast, features, and the auto focus in your camera will focus on the parts you’re demonstrating rather than the background.

If you were creating a new harness from scratch. Would twisting wires for each component cause problems in an entire harness? I know there's concentric twisting but I don't quite understand because I seen straight and twisted wires ran in a factory harness.. I guess basically what I'm asking is when do you use twisting and straight runs?

Should we ground for a led in chassis or -ve terminal of battery 🔋? For a 3ampere 12v 36watt led strobe light? In car?

what's an ACU? Auto Control Unit?

I love the supply of automotive liquids and fluids. Almost looks like a retail shop.

Broomy please answer this, where can you buy the good quality plugs etc local? Super cheap, auto barn and all the usual candidates only sell Chinese junky butt connectors .

A couple of comments. Wire insulation. - not all insulations are the same. Selecting a wire based on the thickness of the insulation is not necessarily the wisest thing to do. If you are running wires in the engine compartment or outside the cab of the vehicle I would suggest a cross linked polyethylene because it is far more durable to environmental conditions. And they do come in different thicknesses. (SXL, GXL, TXL) Some of the thinner wires just won't hold up. Twisting wires. - You need to be very careful with respect to which wires you twist together. The main reason for twisting wires together is not because it makes the wiring neater, but rather it has a function purpose. Twisting wires together helps reduce EM interference from other sources. So things like sensor wires, communication wires etc should be twisted together. But you definitely don't want to be twisting wires going to solenoids, relays, coils, or even power etc with sensor wires . That will likely cause problems. connectors/plugs. - First, ALWAYS use weather resistant connectors for anything outside the cab of the vehicle. And they always have applicable wire and insulation sizes. Those whitish connectors, at least the ones you have, are for 18-16 awg wires, not 20 awg. That's why it didn't hold when you crimped it to a 20 gauge wire. They always say what gauge they are for. Also when you are connecting to an ECU you would have to use the matching connector. You don't really have a choice. They are also not sealed so if you use those in any sort of application exposed to the weather they will corrode. Also, those little tabs will actually hold extremely well against pushout. The movement you showed is really irrelevant. It's not going to contribute to wire fatigue. The movement is simply because they are not sealed connectors. Those Packard Whether pack connectors are very good, so are the Deutch connectors. Again one thing to be careful about is the size of the insulation. As you can see there is a seal on the back side so if you are using very thick insulated wires you might have trouble getting several wires into the connector even if the gauge is correct. Always use the proper crimping tool for the connector. Each brand tends to have a unique crimping tool as you showed. Also, some connectors require you to push the wire through the connector first and then crimp on the pin and pull it back. Some require you to crimp the seal to the wire and pin at the same time. All your wiring harness should be then wrapped with some sort of secondary loom or covering. Especially if you are going through a bulkhead or firewall. And always secure everything.

i use 16 gage whier

I didn't know those automatic strippers were 25$! Figured they'd be like 80. I been stripping wires with a lighter and fingernail my whole life

What is the advantage of twisting the wire ? I want to install led strobe lights on my truck for safety and wounder if there is any benefits to twisting the wire ?????

Cool. I don't like twisting wires though. Seems unnecessary and can cause its own problems.

Did you forget to feed the magpies? I hear them calling.

Hahahah I just bought jaycar wire with thick insulation should've watched this first.

I would solder those connectors onto the ends of those wires

The wire that is twisted could be to prevent capacitance.

Point five millimetres squared is veryyyyyyyyy different to point five square millimetres. Stavros

you crimped an unisolated terminal with the isolated tip of the crimper !!!!!!!!!!! thats why it pulled appart!

Shameless Bowdens plug in the background.... 🤔

Mind what you say mate we are all over the world almost everywhere....dare you say solder thats blasphemy.....

Downloding

Sidecutters are crap, use cable shears. Deutsch are also overrated and fiddly. AMP Superseal cheaper and easier to use, albeit not as pretty. Although wouldn't carry as much current as say a DTP

noooo

These thumbnails sure are getting annoying.

Definitely don’t recommend twisting the life out of your wires like that….🙄

NEVER EVER PULL TWIST OR STRETCH WIRE IN ANY WAY !!!
