harness

hey im just trying to figure out how to deal with this harness and computer. i rather run the fuse panel for protection of everything but im not sure on what wires to cut or use. im running a 5.3 with a 4l60e out of a 2002 silverado. im gonna run autometer gauges and i want efans. i know most will say nelson tune but how does that whole system work? how much? thanks.

hook the wiring into your existing fuse panel. All your original circuits were protected by fuse so all you have to do is splice into the existing wiring.

a NP harness is 650+ shipping well worth it!
