I have a 1997 30th Anniversary Z28 that was a infrequent driver and in the interim between start-and-drives I found the wires on the top of the LT1 chewed up. I am inquiring where I can find the actual part number for the harness and where would be the best place to get it from.
Thanx for any help.

 

Bill,

I had good success for my 1994 Trans Am LT-1 with Painless. They ain't cheap, and one or two things needed a little work, but it was fairly straightforward. I have heard that some electrical wiring lately has insulation derived from soy-based materials, so the wiring is attractive and tasty to some varmints. You might want to check about that problem, first. If you have that stuff, maybe Painless can advise on what can be done. Rodent-chewed car wires are a big problem in Europe now. Anyway, this is the product I bought; the Painless folks can tell you better than I can.

OP

If you are handy with a solder iron and heat shrink....you can repair the harness. Depending on how much munching the rats did, it may be easier to remove that harness and repair it on the bench

You will want to use grey stripe split loom in the various sizes you will need and some good quality electrical tape

Painless wiring makes good stuff which is a option posted. If you "roll your own" on repairing it you will save some $

 

Bill,

Another option, if you can see ALL of the damage, is brush-on electrical insulation. You will need to spread the wires out, then paint on a coat or two with a small brush. If the metal conductor is damaged (not just the insulation), then you would need to add splices here and there. Protect it all with high-temp spiral-wrap sheathing, which may discourage the varmints, too.

Best wishes.

 

After you get it fixed, here is a fix for the critters. Sprinkle a bit of Cayenne Pepper on top of the engine. Worked for me. And I drove the car almost every day.
