Where to get a wiring kit?

[polaris3400]

My friend is looking on doing a "rat rod" build using a variety of parts. I do not know everything about the project but he wanted me to ask you guys,

"I need the wiring from under the dash to the firewall and from the fire wall to the engine, has to be from a 1987-1991. where can i get this as a kit?"

I'm posting this for a friend. I cannot answer all questions but I will ask him for any information, if any that you would need.

Thanks.

I would say...a donor truck. I've never seen tge wiring available, I would tell him to go to a pick and pull and spend a day yanking the wiring out of one out.

Ron Fransis wiring. They make kits that are very good and reasonably priced. I build custom cars in my shop and have install several.
