hey guys, i just got the electric fans for my truck and now i dont have the money for a nelson harness and i've built a harness for a buddy's car with a diagram but i don't seem to be able to come across the right diagram for my sierra to build a fan harness... my pcm is already tuned for it and yes i want them to work with my ac... anybody have a diagram or maybe even a harness they wanna sell me cheap?
