Hello, i bought 1987 iroc-z and the previous owners had thrown away the wiring harnesses which is under dash and floor carpet. Do some body have pictures about the wirings in car and wiring diagrams? I appreciate about help and sorry about my bad english, i am from finland

 

A service manual on cd might be the best way to get information

 

For a complete rewire job, you're going to need more info than that which can be posted here. Search ebay for a copy of your vehicle's Factory Service Manual (Helms); they come up for sale fairly frequently.

 

Your two best options would be to buy some used harnesses for your specific 87 IROC (best choice here) or to buy one of those aftermarket harnesses ("Painless" is one company who sells them) , which is a distant second in ease of solving the lack of wiring issue. If you were heavily electrically inclined, the third & final option would be to build your own harnesses from scratch, I've done this for several cars & motorcycles over the years and you'd be surprised at how much wiring even a car as simple as our's has .....

 

I hope these provide some help
