I was wondering if anyone could help me. I have an 87 mustang gt. my old dash harness was in really bad shape. I'm surprised that anything worked properly. The wires were cut, plugs were undone etc. so last week I bought a replacement on eBay. Just the other night I installed the new 87 dash harness. When I connect the battery(key turned to off position) the parking lights turn on, fuel pump primes and some dash lights turn on. When I pulled my old harness out I labeled everything and took good notes. So I am racking my brain why something like this is happening. Please if anyone can help.
