For you guys that re-wrapped your wire harnesses… what different sizes do I need, and lengths... also what brand/type did you use? Want something better then the cheap brittle plastic. I want to remove all the old dirty/greasy stock stuff and redo it.

I just used generic wire loom. All seems to be about the same. 3/8" or 1/2" and some bigger sizes.

For electrical tape, use the 3M stuff. The other brands tend to lose their grip over time or when cold. The 3M stuff is a bit more expensive but works the balls.

I am in the process of redoing my harness
I did a little bit of research on what is best to use and I found Tessa tape works great I Purchased it from Amazon
They have different versions some as felted and used inside the car to cut down on rattling noise the other is a cloth like Matt tape design for higher temperatures and chemical resistance inside the engine compartment it’s supposedly used on hiring in European cars anyway I think it works better than standard electrical tape even the good stuff like 3M super 33 or super 88
After removing all of the stock fox body loom the hardest part was removing the hardened electrical tape or use a quality razor knife and after about six hours had the fuel harness completely stripped down and recovered much more flexible than it was
pretty satisfying job
Here are some pics

Here is everything stripped down that was the toughest part the old heat shrink tape was hard as a rock very difficult to cut off without nicking insulation on wire

Here is the finished product
My fingertips are sore but it was worth it

Nice job!! How many rolls did that take for that harness? Trying to figure out how much to order. Thanks.

Oh man none of this looks fun! Great job for you guys that did this. I’ve been considering at some point doing a wire tuck and running an all new wire set up like the American autowire kit. Would that be crazy, pointless etc. I’d like to clean up the engine in the future if and when I repaint the car and figured if it’s old brittle wiring, then you make it even harder to reach by tucking it, wouldn’t it make sense to update all the wiring. Honestly don’t even know what that would entail besides a bunch of bucks.
