81 T/A wiring issues
« on: August 08, 2019, 10:15:16 PM »
I recently purchased an 81 T/A with no motor. I put a 400 in it. The issue is the wiring for the motor and under dash. Of course I'm not using any of the computer components originally on the 81, so not really sure how everything should be connected.  Does anyone know where I can find a good schematic.  Any help would be greatly appreciated

If it were me, and not going with the original computer controlled engine, I would go with a new abbreviated engine wiring harness's from one of the aftermarket wiring specialists. Like Painless Wiring or Ron Francis, ect.,,,,,,

Carefully remove the factory engine wiring harness and the computer and store them just in case at some point someone may want to put the car back to stock configuration. Doubtful, but you never know.
