I also need a SD Engine and Dash harness from a SD Firebird
The dash harnesses were different in almost every year. Mainly in the fuel pump wiring. The C207 connectors need to match years or re-wiring will need to be done.
I need the 88TPI harness more than the SD. My 88TA is ready to run as soon as I plug it in. The SD harness I'm using for a turbo conversion in an 88 TBI formula. I have a painless that was given to me but its more of a PITA than painless.....Plus the factory just looks better to me.
i have a 91 gta i can help with the body harness...just the inside harness, i also have a front head light harness from a 91 formula [ does not have fog lights] no engine harness...if this will help you at all....
