Wiring Question again.

I got the 93 EFI main wiring harness.My car is an 87.

Here is my question.

The 8 pin brown connector on the drivers side by the srt tower. I have figure out where 3 wires go to. Can anybody help to figure out where the other 5 go to. I have looked at wiring diagrams and cant figure it out. The brown connector is for the dash. On my dash wiring harness I dont have that connector. I have a black one and a grey connector. I cant find a dash wiring harness.

Wires I figured out

Coolant temp sensor
TFI Module
Ignition Module

Can anybody help me.

Thank you. You are the man jrichker. I was waiting on you.
