91 cas wiring help

[BoostedTT91]

The 91 talon I bought someone cut of the cas harness and wired in a 90 cas. I bought a new harness for the correct 91 cas but the wire colors don't match up with what I have on my engine harness. The new pigtail has white, yellow, red and black wires. My engine harness has white, red and 2 black wires. One back wire is a heavier gauge than the other black. Anyone have any idea what is what?

So it's the same wiring for a 91 then

Yep. The wiring, colors and sizes and all, on the engine harness runs to the same place for both '90 and '91+ models. The '90 CAS with its built-in pigtail wires up to the either harness (sans connectors) as Bryan pointed out in the thread I linked above.
