Having problems dealing with shotty so called out of work mechanics. I just ordered my harness from Street and Performance for the computer side of the engine. I had a complete wiring harness for the 4.3 that goes to the firewall, but I called myself helping a mechanic out of work who has kids do some work for me. and the jackass cut all the connectors off the harness, and other wires for no reason, but to say they needed re soldered!!! does anyone have a diagram or wiring shematic for this wire harness?
 
That is a pain in the butt! You have three things going on: the Buick wiring, the Chevy wiring and the aftermarket wiring. Some of the wires might be the same color?

A very difficult job sometimes can be broken down into smaller,separate tasks. Are you trying to get everything in the dash correct, or just get it running? I've had to do this a couple times. I worked on getting the car to run, then went back and hooked up the gauges and stuff.
 
Cool! I just received my wire harness that goes to th cpu, I've been looking for the other harness, but hopelfully I'll find one soon, so I can get this thing fired up.
