89 TTA GAUGES/WIRING

[ttanotchback]

Trying to finish my car. All I need is the wiring for the gauges. Im trying to find out if I can use a 1989 GTA V8 dash wiring and just wire the turbo boost gauge? I have the supplement that shows the wiring for the boost gauges other than that does anyone know if its the same...thanks

I think Caspers used to sell the entire wiring harness. Not sure if he still does.

Can you post a few larger pics of your car? It looks awesome. Is it an original TTA that you painted red and put the notchback on or did you convert the engine to a TTA?

I think he swapped a TTA motor into a GTA convert.

I am pretty sure the stock wiring works for the original gauges, but you have to add some for the boost gauge to work. That was a while ago that we did my Camaro, but I am pretty sure I am correct. I will someday be doing it to a 70-73 TA and can't wait.

Mike is right the stock GTA dash wiring is the same as a TTA, the TTA engine harness plugs right into it and the wiring for the boost gauge is a 3 wires that tie in to the map sensor. The TTA is mostly GTA with a few vehicle specific parts which makes this swap is pretty much plug and play.
