I drove the truck home with working lights so really at a loss. Wiring was a snakes nest so figured a new harness was a good thing. Tracing out wires through the stock schematic which this one is suppose to follow. Wondering if the switch to alternator by the previous owner is causing grief? Harness I bought was for an alternator. Need to figure out how pwr gets from bat to light switch.
