Had to change fog light today, little mishap, what a pita trying to get new bracket and light in place. Found a wiring harness laying along front of bumper, looks factory, is 3 wires in a loom that runs back along drivers frame rail and goes into big harness so can't tell where it goes from there. Truck is a 2001 F250 4x4, Canadian sold. My block heater plug runs right along side it, any ideas?
