Today at Ugly Truck, we're wiring up the headlights on this 1986 C10 6.0 LS swap to run through the OEM donor fuse panel. With the help of our trusty whiteboard, Jerry explains how the original 86 C10 circuit works, how the LS donor circuit works, and how we tie the two together. Since we no longer have the BCM, we use a couple of relays to trigger the new circuits. It's a more efficient way to run the lights, and we shaved off several amps running into the cab of this truck.
