Front Signal Wiring Trouble - '80 911 SC

[Davie Boy]

Can someone please tell me which wires go where? I've got 3 wires coming from the car:

1) Black & White
2) Red & Gray (has a white wire connected to the end of it)
3) Tan (also a has white wire connected to the end of it)

There are 2 posts ON THE CAR, just above where the wires are coming out from the car, and there are 2 posts ON THE BACK OF THE SIGNAL ASSEMBLY. Which wire goes to which post... and what's up with the white wires mentioned above?

Thank you in advance.

I'm trying to figure out the same, so I will revive this post. Stupid me for not labelling these!
