Put a 6.0 in a 2000 v6 swapped interior and exterior harnesses to dbw, fuse box everything, ok truck runs like a champ but the headlights wont come on (brand new bulbs in every single socket, no blown fuses and all relays are new and in working order) the left front turn singnal come on when the battery is hooked up, doesnt blink just on constantly, and so is the right indicator in the cluster? Also if you turn on the right signal both tail lights blink, left signal nothing happens, the fronts still dont do anything but stay on, brake lights work fine. Any ideas would be great.
