Jeff, I'll be in the garage all day tomorrow. Swing out and take a look at my setup, if you need. I've also got 2 spare harnesses out of the car + TSRM that might be able to help you out, if you want!
As for online help:
Is the 91 originally a turbo M/T car (damned if I can remember - this is the one you got from Jake, right?)
I'll d/l AEMPro and look through the pinout tomorrow, see if I can help out any more.
