Wiring schematics can be found for free at the public library. Restore the wiring to the way Ford had it. Replace damaged or inoperative parts. If the vehicle is set up to tow something it may have wiring that confuses the way it is currently rewired. Towing wiring is printed on the packages of towing connectors where they sell them new. Rear light sockets for the truck can be at fault and availability may have been why the previous person attempted to change it. Note, any wire you connect to the battery must have a fuse or circuit breaker as close to the battery connection as possible. An unprotected circuit can be disastrous. Problems with lightbulbs and the way they are installed or connect can lead to confusion. Switch concerns and flasher circuits can be affected by the bulbs acting right first as well.
