I am cleaning up the stock harness. I need suggestions as to what use to wrap the wires that are left. I want something that more resistant to oil and fuels than electrical tape.

These folks have a wide variety of wiring items that work well for race car applications.

I know you said you did not want electrical tape but I would recommend 3M Super 33+ electrical tape. We’ve been using it for the last 15 years on engine wire harnesses without complaint and it’s available at Home Depot. https://www.3m.com/3M/en_US/company-us/ ... 633&rt=rud

3m 33+ is excellent electrical tape and will hold up far longer and better than most tapes but will still get sticky if exposed to oil/gas. I use the tape at my real job and have been doing so for over 30 years I won't use anything else. I have found there are just better materials to use in an environment such as our engine bays.

If you really want to go with loom, I've found this stuff stands up to oil really well

That said, many wires will not. Don't expect a covering to somehow protect an oil-free shield to wiring; that's asking a lot.

I used a wire loom similar to what Bill posted. Easy to install and looks good. the trick is to buy the wire loom tools as well: https://www.amazon.com/Wire-Loom-Cable- ... B005DTKNZU

those can be used on any style of split loom, and makes pulling wires through it pretty durn easy. Stuff all your wires into the center, twist the thing to lock all the wires inside, then start pulling. the loom slides right over the tool and all wires inside. Use a little heat shrink, zip tie, or scotch 33+ on the ends to make sure nothing comes loose. voila.

Regarding the materials, looking around on some of the other racer supply sites (Summit Racing, etc), you can get a version that's fire retardant or whatnot. probably a good idea to spend the little bit extra in a race car. Given the quantity you use inside the car, the few bucks are worth it. I might have 30-40ft of tubing inside the car from my switch panel to the firewall and dash.

For wrapping harnesses, there is only one choice. Tesa tape.

Amazon sells it.

It’s cloth and hold up very very well.

Which part number do you suggest for an engine harness?
