How to sleeve your wiring harness 101

[silviapwr20]

Hey Guys, as some of you know, I was inquiring about different types of heatshrink and sleeving a few weeks back. This will be for a new oem S13 SR harness, modified to fit in an S14. After hunting high and low for the sleeving, it seemed as everyone wanted to sell the stuff by 25' rolls and nothing less :( . Eventually I came across an industrial supply place here in Winter Park, FL that sells it by the foot :D . The name is Skycraft: Parts & Surplus (http://www.skycraftsurplus.com) I was so stoked, I went and paid them a visit. To my surprise I got there and found the place packed, you would of thought it was black friday in there or something, haha. They had a zillion different sizes and grades, so I ended up snaggin a few feet of each (for both the sleeving & heatshrink). I then rode home w/ my bounty and began the wiring fun :D . Overall, the process wasnt too bad. Once you have everything layed out, you will get a better idea on where to route & tuck things. You'll also need to de-pin EVERY plug in order to slide your sleeving on :bash: just use a small flat head (eye glass ones work great!) Here's some pics of the finished product. Think I still might finish sleeving the cabin portion of the harness, but this is where I'm @ now (sorry for the thumbnails, my pic uploading service was being wierd)

As you can see, I've extended the injector plugs since I'll be running a greddy intake, O2 was also extended. I plan on running a MAP sensor, so I eliminated the mafs plug (kept wires hidden in harness, just incase though)

really sick, and sweet setup, but how come you didn't wrap it once it got into the interior?

[shmiddy]

dude that looks awsome!!!

That's great. If you don't do too much with your wiring it's best to seal everything up permanently.

Unfortunately I've redone my wiring at least a dozen times now so there's no point in finalising anything :(

In order to do that, I'm probably going to need to depin the ECU plug :cry: I need to find a larger diameter sleeving for that part as well!

Ya, I'm only doing this setup once, and plan on keeping things the same for a while.

BTW how do you properly de-pin sensors and plugs? I know on honda plugs tyou can fucking take them apart. on nissan plugs, it seems they are all molded.

[CamryOnBronze]

This is an inspiration to my project right now... and much needed! Very nice work!

[4sfed180]

nice work. looks excellent.

ive been doing the same over the last week on a VW F3 engine for my boss. the thing is i started with a blank harness.

if you really want to give your car the look of "ready for business" get some Raychem aircraft style connectors. :)

de-pinning the plugs is a fucking bitch, there is a technique to each of the plugs. I'll try to post a how to in my build thread. I'm also in the process of sleeving my harness.
