no headlights tried everything!!!

Hey guys i recently acquired a 1992 f350 with the 7.3 N/A. The headlights were working when i got the truck and just the other day they went out and i have not been about to get them back on.
I replaced the headlights switch, pig tails the attaches, tried with new headlights, checked all fuses. Im stumped and cannot find any wiring diagram for this year truck. Is there anything else i should check?
Thanks in advance you guys have been very helpful in the past.
Austin.

yes there was a plow on the truck at one time and the previous owner took the plow off but left all the wiring for the plow still attached.

Then check the plow's wiring. It may be interfering with the headlights. If you aren't going to plow with it anytime soon, you may opt to eliminate the plow wiring harness.

Well when you posed about the plow i went out and checked the switch that was lying on the floor and 3 connections were disconnected so i put them back on the switch and bam i now have headlights. Would have never of thought that that would have anything to do with it. Thank you again guys i would have never of figured that one out.
