On the taillight socket I am pretty sure that the red is your turn signal, white is the ground and black is the running lights, although these don't sound like factory colors.
Are you trying to wire an after market plug or the actual tail lights for the truck?

Brown is Running and Tail-lights
Green is right hand T/S Brake
Yellow/Black is Left hand TS/Brake

Here is a schematic.
