Okay, my TCU totally crapped out. Leaking cap, grease stains over a couple of micro controllers. I see those shift boxes, and another guy claiming he is manually controlling his tranny over a dead TCU. Well, I'd like to as well.

I have a Hayne's and Chilton's and I can't find the TCU wiring diagram in either.
If anyone knows the location of a '92 Auto N/A 2.0 Eclipse TCU wiring diagram, or has one, I'd be most appreciative. Also, if anyone has any suggestions or would like to explain the theory behind controlling the shifting solenoids, EG -> How to apply power to the wires to up-shift & down-shift, I'd also appreciate it. This looks like fun while I wait for my new TCU :]

Thanks!
