Electrically, what am I getting myself into? I know the 99-02 trucks, it's just in the engine harness, but the 03+ it takes some work. I'm electrically retarded. My engine harness is from an 05 Z71, all the wiring for the auto trans is still there. Allen where you at? I know you've done it. Mic, I know you did it. I want full function, like factory. Running 14's and trapping 114 is gay and I'm sick of it.
