the brake light switch has it's own fuse that is on all the time. test light power at the switch? push the peadel down and both wires should be hot if they are theres more.! turn on the hazard flashers do the brak lights flash brightly? That proves the bulbs the sockets and the wires if they do. if not the cicirt boards in the tailghts can be bought at discount part stores and their better than the ones that came with the truck but they'll fail too. Before buying them turn the flashers on and remove the tailight and unplug it. turn the parking light on tooas you need to see some thing that works also, Find a good ground for your test light and probe each wire of the plug one wire the brown one will be on steady the yellow or green wire will be flashing if the front of the truck is OK the other two wires are the backup light and the ground wire if the test light works and the light doesnt check the bulbs their good chang e the circuirt boards
