I have already checked the fuses and they are good. I have no power going to either headlight fuse and I also have no power going to the heater control switches. I did an engine swap and I installed a 4.3L chevy engine in it and I got rid of some of the electronic components in the cab and in the engine compartment. Tail lights, dash lights, and turn signals work off of switch.
Hi ricky messing with a toyota is not a good idea due the complex nature of it's electronic systems so you really might need a specialist here who knows how it will cost you dearly.

The headlight fuses on nearly all vehicles should be hot all the time (even key off). I would look under the hood as the connection should be at the relay/large fuse panel. Just guessing but if you fix the headlight problem you will probably fix the heater problem at the same time. I would use Bing to find a wiring schematic and print it out. When dealing with an open circuit I sometimes use a very long jumper wire to feed a hot wire directly into a dead circuit. Then I can back trace in the suspect area to find the wire I just made hot for a clue as to where the break is. When feeding in directly off the battery positive terminal, I always hook it up with caution looking for a big spark indicating a possible short. Wouldn't want to fry any wiring! P.S. Before the engine swap was there a wire hooked directly to the starter solenoid where the positive cable hooked up? This would be my best guess for the feed location.
