I have an 87 GTA firebird with Digital dash. I need a wireharness for my car. I actually only need the drivers side firewall harness. I am doing a Tpi to carb swap and I need the harness. I was wondering what years will work. I have a 383 stroker getting installed. I sold my old harness and totally didn't know I needed the firewall plug and wires. I'm an idiiot a guy swaped me an 86 carburated wireharness and said it will work. But it wont. Can someone help me out.
