Hi everybody, new to this site, have been having connection problems with my truck. It started out with the turn signals, then the heater, then the starter solenoid. My truck was just a few months after everything would have been a slam dunk to fix, all of the inline fuses, etc. is a maze of wiring enclosed between the firewall and dash, would be a total pain in the *** to find the problem. If anyone knows of one, I need a pic of a wiring schematic for it. And an easy way of hard wiring the heater direct from the battery to a toggle switch inside the cab; what would be the right size wire and back up fuse?

Truck is a 1977 Ford F250 Camper Special, made in the latter of the year.

Thanks for all your help,

i wouldn't run a new wire to the battery. i'd run it back to the original fuse in the fuse box as long as you have power to that fuse. if not i would suggest finding out why the fuse doesn't have power before i went canniblizing under the dash. i dont have any pics but i don have 78 with the dash torn apart i counld help you trace wires if you tell me exactly which ones you want to trace.
