I had this problem once, after about 45 minutes of messing with every harness and shaking all the wiring and checking fuses, I still couldn't get the headlights to work. Eventually I messed with the high/low switch in the cab, and apparently it had been stuck between the high and low positions. Pretty frustrating knowing this is all it was. You may have already tried it, but it took me awhile to even try it! Also, not sure but I've got the relays installed for the headlights, and you might want to check that they are working.

The headlight switch itself is known to burn up in these trucks. Mine melted and left me with parking lights and nothing else.
