Invisibleman13 Posted October 22, 2022 Share Posted October 22, 2022 Hello all. I'm trying to replace the tail light sockets on my Bronco and have run into an issue. The wiring on the new socket is a generic "red, black, white" configuration that doesn't match the wiring coming from the truck. The replacement sockets are Pico brand that I got from Bronco Graveyard. Driver side wiring is "brown, black, green w/red stripe". Passenger side is "brown, black, black w/pink stripe". I could really use so help so I don't have to go through a trial and error method. Any help is appreciated. Link to comment Share on other sites More sharing options...
Gary Lewis Posted October 22, 2022 Share Posted October 22, 2022 I haven't found any Pico wiring diagrams so would offer this. First, Ford uses black for ground and brown is tail light. So the black/stripe wire should be the stop/turn wire and will connect to the light green/orange on the left and the orange/light blue on the right. But, you can check, visually. The brown wire should go to the longer filament and the striped wire goes to the thicker, shorter filament. Longer filaments have more resistance and are dimmer, which is what the park/tail lights should be. Link to comment Share on other sites More sharing options...

BigBrother-84 Posted October 25, 2022 Share Posted October 25, 2022 For 3 wires Pico socket (tail lights): Pico White = Parking = Truck Brown Pico Red = Flasher = Truck Right or Left so Orange or Green Pico Black = Truck body ground Black For 2 wires Pico socket (such as backup or sidelights): Pico White (or maybe Black)= Truck body ground Black Pico Red = Truck live positive wire (colored one).
