Ok seen the site but needed some help so I made an account.Hopfully someone can help.I have an 89 z that had an 85 TPI setup in it, well that started to take a crap and so I found an 89 TPI harness for cheap in a firebird at the junkyard.I repaired all the plugs and rerouted all the wires and cleaned it up per an 89 camaro.Had a chip burned to bypass the vats pluged it in and nothing.Grrrrrrrr, not very happy right now.Are the pins in the bulkhead for the firewall the same, Im missing fuel pump and injector pulse.This is so frustrating.This is my daily driver so I really need some help here.Thnx, Dave.
