Re: Looking for 91' 305 tpi engine harness
I have one from conv 91 z that the the red relay wires have been cut. It can be fixed easy. It was that way when I bought car because some clown put junkyard carb motor in it. The harness is unbolted from the c100 and unplugged from ecm and gently removed from firewall. If interested I can send pics. Make offer
