I have a problem with my cars engine harness at fuse box under hood!! Battery acid leaked on to wire harness and started eating away wires I have been replacing them one by one, wanted to know if I could just buy a harness and what is compatible with my car? I have a 2001 grand prix gt with sunroof/onstar and HUD. I don't know if I need a certain wire harness or will just anyone off a old gp will work? just need advise thx :th_scratchhead:
 


I've got an entire ON-STAR system if you want it...PM me if you do.

Other than that I have no idea about wiring. You can try going to a junk yard and cutting out the wires you need there and splicing them into your car...
 
you can get a whole harness, gonna need the whole engine bay harness that goes to the pcm and ends at the firewall? not sure if it has a bulkhead connector or not, never looked. at any rate, its gonna be a pita.
 
yea i don't need the onstar unit just the whole engine harness I have been splicing wires and putting new ones on but with about 100 wires it is a messy wire harness now and I am not done just wondering about the harness.
