Looks like I need to do a harness to get rid of all the splice and dice the POs did to my under dash harness. what years should I look for? Will a camaro one fit (doubtful)?

 

digital dash or analog?

 

Analog. Auto

 

Definitely don't get a Camaro harness as that won't be compatible with your GTA. As for which years to look for for a compatible harness I believe any between 85-89 will work. Just make sure it matches up with your power accessory options and all should be good. You also don't have to worry about looking for a harness that came from the auto, as the manual and auto are the exact same.

 

The best matching harness will come from an 88 Firebird with TPI. Second best choice would be from an 89 Firebird TPI.

There were a lot of changes from pre 87-to-88 so I stear clear of those if possible. ( 87 dash harness stops at the drivers kick panel,.. 88+ dash harness ends all the way at the back of the car ) 90-92 are Speed Density TPI's so I'd stay away from those unless you are converting your TPI to keep things 'simple'.

 

There is an 87 firebird that just got to the junkyard. It is most likely a V6 car (havent seen it yet). Would the harness out of that car work?

 

Please; Re-read post #5.
