Tail light/directional light wiring - F-Series & SuperDuty Diesel Forums

Can someone tell me the color coding for the let and right tail light assembly. Particularly interest in the directional and ground wiring. Or at least direct me to a wiring diagram for these assemblies.

What I am looking for is this. When I pull the tail light assembly from the truck, the large bulb (tail light, brake light and directional) has three wires running to it. I assume each wire is for 1 of the three functions. I am trying to find out which wire controls what and for each side (L and R).

I am replacing the incandescent bulbs with LED bulbs. I need to put a load resistor in the line, but I don't know which color wire is for the directional on each side.
