I was hired to complete a project for a customer. The owner has a 94 1500 manual with a blown. They had a "friend" with a 99GMC c1500 with 4.8L. He swapped the motor, changed the flywheel, and could not get it to work. I read somewhere they sold a wiring harness for the swap and was wondering if anyone knew where to get it? Or if anyone had a quick guide of wires to save me some wire tracing and time. If not will do it myself and take pictures for the next person who does the swap!

What he said ^ there are a lot of people over there that have done these and have diagrams. LT1swap.com has a lot of info too for the vortec harness.

Yes sorry about the low quality pictures was just showing that it's in process and not a pipe dream. I've gotten it to the point of starting and running for a second, however, they do not have the BCM so I'm trying to figure out which 2 wires to put a resistor on to bypass the Passlock (ignition is original in car not the one motor came from of course) so my best guess so far is the yellow and the black/white wire in the plug in picture. Any thoughts or anyone know for sure or should I keep digging. Or does anyone know how to bypass passlock from killing injectors another way?
