Need help identifying forward wire harness from '88 3.2 ECU
 

I'm installing my AEM computer and have talked with Andrew about where to wire in for the tach and ignition, but I wanted to get a positive answer on what these wires were just in case they have what I need. It would be much easier to splice in to wires at the driver seat than behind the dash.

This is the piece of the harness that splits from the main harness at the driver seat rail and goes forward. It goes up into the frunk from the left side of the drivers footwell, right next to a blue hose which I'm pretty sure is part of the brakes.

There are 8 wires described as follows:
-Pretty thick red wire
-Thick red with green stripe
-Thick black
-Medium black
-Small black x2
-Small green with yellow stripe
-Small yellow

I only have the bentley manual for the SC, so don't have the wiring diagram readily available. I'm searching the internet as well, but it has been difficult finding a high enough resolution of what I'm looking for.
