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!
