I like the rope method you use. Been doing the same thing with different colored yarn myself when doing complete car harnesses. I then use the yarn as a template for lengths so i can put everything on a board and run everything. To some it may seem like overkill but when you are doing a complete chassis harness on top of an engine harness it is well worth it time as wire and connectors aren't cheap when you screw up.
Just wow. Great video, and I’m not even working on cars. I’m going to use this technique for an experimental aircraft I’m building, specifically the panel harness where there are lots of connectors in close proximity and it is tough to visualize where the trunk should go. Thanks!
Thanks mate, now I just have this stuck in my head haha - ua-cam.com/video/notKtAgfwDA/v-deo.html Thanks for the comment though! Zac knows his craft well :) - Taz.
Can you recommend a good general purpose crimping tool? Also, can you recommend a brand or variety pack of heat shrink/ solder electrical connectors? I don’t do a lot of wiring projects, but the few that I do, I want to do correctly. I usually solder my joints, then cover with shrink tubing. Any help or advice would be appreciated. I just started following you. Great videos!!
Although as mentioned, unnecessarily long, or nonsensical routing is a proper cost consideration. Labor and associated inefficiencies are important considerations as well.
Hot glue can also be a poor man’s sealing epoxy (black stick) when heat is applied, the excess hot glue bleeds out of the boot and protects it quite we’ll. Works especially well with adhesive-inner heat shrink
I built those harness boards. Terminated the wires. Routed the harness on the board. Tapped them by machine. The only thing I didn't do was the wire cutting. Man o Man was that some tiresome work. Some harnesses got Braiding covers on them. That machine SUCKED to operate. Finger Munching POS that was.
Supporting wiring onto brake lines is a TERRIBLE Idea. I have seen cars catch on fire and leak brake fluid because of this. Sand dust from the road is e perfect abrasive and even the slightest vibration can rub through the insulation and make problems. I had to fix a lot of strange problems because of wiring like that. If you can, use the stock cable supports, DO NOT support wires that go to the engine on sharp edges, brake or fuel lines. If I have to support wires on edges or brake/fuel lines, i usually cut a piece of hose just big enough and cut it through the middle and then put it on the line or whatever it is. Very cheap, reliable and easy trick. Also, it insulates perfectly and is abrasion resistant.
This is for a race car that is constantly being maintained, not an unmaintained daily driver where everything is only looked at once it has broken 😀 - Taz
@Simeon Petkov let's try and inject some common sense here. It seems that you're suggesting that a wiring harness is going to abrade through a brake hose and result in a brake fluid leak which is laughable. The brake line is a lot harder than the DR25 covering the harness, so it would be your wiring harness that would fail under that scenario. One of the reasons we use DR25 to cover our harness is that it offers exceptional abrasion resistance, however that being said, if the harness is properly secured in the first place you'll have no relative movement and abrasion becomes a moot point. As you'll also note in the video, Zac specifically mentions that you shouldn't be securing your wiring harness to anything sharp. @Jeff Matthews to follow up your comments, in close to 20 years in the industry I've yet to see a brake line abrade through anything and if your wiring harness is subjecting your brake lines to excessive heat then you've got bigger problems to worry about than how you secured your wiring harness. As above, if the harness is secured correctly there is no danger of abrasion to either the harness or the brake line. We stand behind everything we teach 100% and we're very comfortable with what Zac demonstrates in this video.
@@FightingSportsMedia nice one man. I'm sure you're on the right track but if you wanted to see what Andre did for the SR20 swap you can find his sheet here: www.hpacademy.com/forum/professional-motorsport-wiring-harness-construction/show/documentation-example-sr20-engine-swap - Taz.
Yes sir! You're going to find wires in your fuel tank too most likely, and this is also what Cosworth do. Use your brain and there is no risk or issue with this - Taz.
@@hpa101 Nylon cable ties are well documented for cutting through hard fuel and air limes, dirt impregnates the tie and then it acts like an abrasive, obviously it can be done but is is not best practice. and btw use your brain was a bit cheeky,
Yup! There is always the option of getting someone to create a harness for you. Our goal (which we reached) was to produce some courses that would work out at a lower cost than this when you also include the materials for those that do have an interest in learning and having the satisfaction of building their own harness :) - Taz.
@@hpa101 I understand that. But for someone that has never done it this seems impossible, I have been there. 3 years of tech school and about 20 years of working on cars harnesses are easy and the hard thing still to do it rebuilding a automatic transmission.
J.R. Beumel for sure, everyone starts somewhere, but you're better to start than just wonder if it's something you think you're interested in as you yourself did, and if not, get someone to do it for you. Easy 😎 - Taz.

Outstanding example of harness planning and unbridled passion for harness planning.
Loved the video, one day I will be a wiring guru!
Wish i knew this when i built my harness. Damn
Ahh well, if there is a next time it will be easier =) - Taz.
Bloody clever way of doing it. Good stuff boys

Glad it was helpful!
Love the finesse 👌 like a surgeon

Hahahahahahaha oh, too good!😂
Cool ideas thanks
Awesome video as always..hope you guys do a twin turbo setup tutorial..i think I want to go twin turbo straight 6 e30
Excellent video
Amazing expertise. Thank you.

Oems sttach speed and abs wiring all the time to flexible. Brake Line
Top 👏🏿👏🏿👏🏿👏🏿👏🏿
Does the course include a basic guide to documentation of the harness, i e DIY wiring diagram?
Sure does :)
@@hpa101 Great!
Thx for the reply :-)
Would laying a harness over the spark plug coils cause any interference
Directly over a coil? Yeah it could cause interference in highly sensitive digital signals
Im about to start putting together my haltech unterminated harness. Super nervous, ive been procrastinating for months now lol.
Woo! Take your time, triple check things and you'll be fine mate =) - Taz.
@@hpa101 Thanks man! Ive been working on a spreadsheet with all the inputs and outputs and everything.
