Vintage Thunderbird Club International

79 T-Bird, Instrument Cluster 14 pin connector. Is is possible to tells which 2 pins light up the ALT light bulb. My battery will not charge with a bulb in these two pins. My whole plastic crumbled when I removed it from the car. That is why I am searchng for the 14 pin connector wiring diagram.

I am searching for a diagram for a 79 T-Bird with a 14 pin connector with Printed Wire Board # D9SF-10C956. Any suggestions will be greatly appreciated.
