You guys have been so helpful on my automotive journey. I’ve been a bit slow on wiring my car but I’m excited and even ready to take it a bit further by engineering my own fuse box. It would make the power source much simpler than having 2 split fuse boxes that my car comes with factory, and I could treat it like a pdm. I’d like to produce a factory or better quality harness before my project is sold
I’m still unsure about what the actual job of the kapton tape is for. Other then helping to provide strain relief why is it used in place of tradition electrical tape? I heard the part about making it easier to service wires if needed and to prevent the adhesive of the molded boot to settle on the wires. But is there other reasons why this tape is used?
Electrical tape is not a permanent material in the conditions typically seen in an automobile; the glue will release and the vinyl will stretch, roll, and otherwise distort considerably, making it very unsuitable as a strain relief.
@@TheSteelArmadillo this happened to my radio harness cut and resolder job, all the electrical tape was unraveling. No issues yet but it looked like a nightmare
Part of my solution is to zip tie the electrical tape around the wires. This prevents unraveling and provides a little more bulk that allows more margin for chafing against metal things
Is it normal for a coolant temp sensor to have continuity between the wires when you measure at the sensor connector? In none auto applications a tempereature sensor may have a resistive divider at the ecu side but I dont imagine an automotive system requires the level of accuracy that would require 4 wire measurement so I assume the continuity is due to some break in the wires but always good to get a second opinion.
It's peeling off a concentric layer where the sequence is explicitly defined so he knows the next group is a certain sensor and so on for the group after.
@@JosephHHHo but one layer had 4 or 5 of the same color wires. I understand concentric twisting and everything but it's having so many of the same color wires. I like to be able to tell what wire is what just by a glance
@Peyton instead of trying to commit a bunch of random colours to memory it's easier to just check your documentation like Zac does, and then he will check the ident tags, which is exactly the same as checking fully coloured wire and associate colour bands. What he has done in the meantime though, is saved a ton of time and money on not having to source, stock and sort 100 different colour options and instead can bulk buy white, generally at a bulk discount to boot. Both options will get you there, but that is just a little insight into things, hope it helps. It certainly can look intimidating if you assume you're just plucking things out of thin air.

Typing as a world-renowned video production expert and world-champion watcher of the TH-cams, please allow me to provide some irritating feedback. Something about this video is super super annoying. Even watching this video at 2x speed, it drags on and on. Most of the video is so god-fucking-damn boring but tantalizing because of the excellent reputation of past HPA videos and the visuals of the wire harness, which looks unusually good. Even the characteristic color of the kapton tape is doing a better job selling the video than the forever-long lecture. Also, the interesting part is so fast you can hardly see what is going on. Even at 1x it's time lapsed to the point of not being smooth video. TL;DR this should be a 2 minute video of applying kapton tape with a voice over for the (valuable) content. It's a stretch limo when all we want is an Uber.
haha cheers for the feedback delivery mate =) This is taken from a course material, rather than the sole focus being on it as a YT release, and you're not wrong but we do like to cover all the bases in our explanations. We do always take feedback onboard though and love to hear it, good or bad, so I will pass this onto the team here too. Appreciate it - Taz.

Now I've booked the Hpa VIP, very nice. Greetings from Germany!
Welcome to the VIP crew mate! Hope you enjoy years and years of value from the current and future content - Taz.
This is priceless, thank you!
You're very welcome!
Lovely and timely

Never use duct tape on duct work, never use electrical tape on electrical work.
Electrical tape is not a permanent material in the conditions typically seen in an automobile; the glue will release and the vinyl will stretch, roll, and otherwise distort considerably, making it very unsuitable as a strain relief.

@@TheSteelArmadillo some electrical tape will also become brittle with time
I think he nicked one wire in the sensor branch?! Maybe?

You're welcome!
Newbie here. Pros/cons kaptontape vs lacing yarn used in avionics ?
They are used for 2 different purposes - Taz.
nice
Hat is the tape you use where you branch off?
Kapton is the brand - Taz.
How do you tell which sensor is which when using the same color wire for all the sensor
It's peeling off a concentric layer where the sequence is explicitly defined so he knows the next group is a certain sensor and so on for the group after.

I'm still a bit confused on how he will identify each cable?
Ident tags, labels, documentation, just like you would if the loom was full of different coloured wires - Taz.
