The 1991 speedometer is cable driven and the 1992 is electric and powered by fuse #8 that also powers the dome light.
But if you have that fuse relay box as in post #17 above than it is a 1992 or newer.

As the speedometer is working, fuse #8 is good as with the engine bay fuse.
Check the dome light grounds. They are usually grounded through the mounting screw to the cab. Other problem could be a bad wire harness along the driver's side floor under that plastic trim that holds down the floor mat/carpet. Possible another ground strap in the rear of cab close by the seat belt re-tractor(not sure on that, have to check the 92 F150 I have)).

Issue is probably isolated to the switch/connector. Headlight switch is a known weak point. Replace the connector and switch. Shouldn't require dash removal. Consider LEDs to reduce the load on the switch contacts. Also consider a relay harness for the headlights; even though it's a different circuit, it's part of the under-engineering of the headlight switch, and a failure there may cause damage to other wires / terminals on the switch and connector.

no the connector is not damaged. About half an inch down the wire from the connecter the insulation is melted to ***** This is on two wires one green with a white stripe and the other black with purple stripe. The green one is the same wire as on of the connections on the dome light. Couldnt get pics today btw srry. I will try to tmw. The instrument bezel is back on and didnt have time to take it off
