I had purchased a 87 Trans Am GTA eith digital dash, 350 TPI and it had a engine fire. My question is by the ecm there is a connector that has six holes for wires but it only uses 3. I think the colors are tan, pink, and purple, need to double check. it goes with the computer wiring. What does it go to? I had bought a wiring harness from a 87 Iroc with a 350 tpi but it does not have this connector.

I went out and double checked the wire colors and there are 2 pink and black stripe wires and 1 brown wire.
