"What's the easiest way to wire an LS swap?" is a question we hear a lot, and here's your answer! We're using the original 5.3 wiring harness, PCM, and fuse box, and while all those wires look intimidating, it's actually really simple. It only takes 3 wires (technically 4) to make this truck start and run. Firing it up for the first time is always a little nervewracking, but this square body started right up and sounded great right from the start.
