I just bought a project from someone, 1994 sidekick that is getting a 2000 2.5L and auto trans out of a GV, the previous owner sent the harness and computer to trail tough to be modified for use in the tracker. The wiring that needs to be spliced is all labeled (about 20 splices) to be hooked up in various locations.
I will keep you guys updated once I get my shop cleared out and get the new drivetrain mounted and start the wiring.
