Heat wrap for electrical wires? What do you use?
I am looking for some ideas as to how I should heat wrap my wires.
I have a 90 l-98, I modded it a bit and have some issues with heat, mainly the temp sendor wire on the passenger side head, some of the starter wires (headers) and the main wire harness on the back of the computer, which runs across the back of the engine, I has completly fallen to pieces and is starting to show signs of heat damage. And the O2 Sensor wires have burnt up the heat wrap on them as well.
I plan on doing more mods and I dont want the electrical wires to be an issue.
I picked up some foil looking stuff with fiberglass inside, I had this around the head temp wire, it burned (crispy) up as well as the wires instalation.
I was debating on running the wire into a small diameter rubber hose, then running something over the rubber hose. (foil/fiberglass or maybe a steelbraided cover) Would this cause more problems?
Would putting the wire in a piece of flexable metal tubing make it cook inside like a baked potato wrapped in foil?

That is the company, I used the heat sheath from them, it burned into crispy pieces.
I was thinking about using something like the "cool tube".
I also used the header wrap from them, and that worked well. Just need something stronger then the heat sheath I guess.

I got the DEI starter blanket, as well as the DEI tape on my critical wires near my headers as well as a piece of DEI on my EGR tube from Header to manifold. Still thinking about the plug boots........ :yesnod:

Electrical Insulating Tape
Any good electrical supply company will stock fiberglass electrical insulating tape with thermoplastic adhesive. It is white incolor, and is used for high heat applications. I use it and like it. Home depot does not stock it. I used it on wires near my headers.
