This is the best I can offer from my chiltons. Basicaly shows a harness that has the 2 fog lights the switch an end that goes to batery and 4 other leads but dosn't indicate what they are. None of the other wiring diagrams have anything on lighting. Hope it helps. I'm thinkin they didn't have relays, just ran thru a high amp switch straight to the lights. I could be wrong.
