Tail light wiring.

[Germy]

On the tail light, I have red, brown and white, on my harness I have the reverse wire, brake, ground, light, and turn. All wires on the harness are diff colors. Can someone I'd the three wires coming from the light housing and which wires go to which harness wires. Not sure. Seems as though two wires will be going to one light terminal, wher does the ground go?

Not sure this will help, but this is how mine works. I have a flat connector
the first one is blank,
the next one (white with gray stripe) is my back up lights.
next is the pass brake light (light green)
than drivers brake (dark green)
than tail lights (white)
the last is pink and doesn't light up anything
Thats the best I can do for ya. Remember mines a 83 so might not be the same. I just ran a hot wire to each connector and looked to see what was lit up.

The pink one is the gas gauge sending unit.

I can't believe that I didn't think of hooking a hot lead to them! Thanks for your input!
