69 fuel gauge wiring

I am in the process of returning a long time 69 drag car to street duty. I'm having a lot of luck, but I'm stumped on the 3 wires that go to the gas gauge. I have the dash out, and the harness is remarkably complete, but one of the things missing is the 3 wire harness and plug that runs the gauge. I have a decent wiring diagram that shows a pink wire and a tan wire running to it, but what is the third wire? And which color goes to which of the three spades on the back of the instrument cluster. Thanks in advance for any help.

Re: 69 fuel gauge wiring

The third connection is black (a ground wire). In the original set-up, there are actually (2) black wires connecting to this third lug. This connection was used as a splice point for two black ground wires to connect.
