I've been wanting to clean up the wiring mess under the hood for a while now, and was thinking about using some of the wiring loom stuff like you see on American Chopper where the loom shrinks & grows sort of like "Chinese Handcuffs" for want of a better explanation
I found this web site: https://www.wirecare.com/wc_splashpage.asp And they have the wrap I'm looking for... they also have fire resistant, and stuff big enough to actually cover hoses & such.... I'm ordering enough to do all the wiring under the hood....
Thought this would be interesting to share!

3M sells high heat rubber tape for high heat and voltage applications, it is red in color. It can be special ordered from Fastenal, I dont know if they are in the States but they do have an office in Vancouver. Heat will be more of a consideration if you route your harness on the drivers side, or you have unwrapped headers or something. If looks are your only consideration, you can route the main run outside of the engine compartment, along the top of the fenderwell, but I would recommend shielding it from slung sand and dirt from the wheel. You can use laundry cable to mock up your main run and plan your branches to get an approximate shape, then remove it all and run your wires on a pegboard, the advantage of this being if you have to run the harness through a bulkhead, any fitment problems will show up beforehand. Nothing worse than fabricating your harness in place to find out it isnt removable because the openings are too narrow to pull branches through. Its tempting just to put harness plugs in a tight spot but each connection is a potential spot for corrosion and voltage drop. I find this kind of work a lot of fun and I think you will too.
