I had my grill off the other day and found these two wires that come out near the horn on the passenger side. I guess the PO cut them off at the connectors. I know I'm being lazy, but can someone tell me what they are for?
I would second the driving lights guess. Do you have any unaccounted for switches in the truck? Some folks wire them up directly to the high beam circuits so it probably worth sticking a multimeter on the wires and turning on the high beams or fiddling with any other switches in the cabin.
If memory serves those aren't the fog light connectors, plus the don't look quite long enough.
@SeanBaker right side of the dash bezel bottom switch marked with a 2, mine only works when the hi beams are on which is correct for my province but changing in the spring to on demand.
Button? I would expect a rocker or toggle switch for driving lights.
Greisinb's advice is good. I would use a light tester instead of a multimeter, but either will work.
Here in Alaska most people call them "moose lights:", and the relay is generally wired so they only come on when the switch is on and the high beams are on.
