I got a gauge cluster from Classic Instruments. The pins in the gauge cluster at 1, 2, and 12 have no use in the new gauge adapter.

Pin #1 went to the alternator
Pin#2 was Y-d into the ignition switch and the other side went to the proportioning valve.
Pin #12 went to a junction block in the engine bay.

Since this gauge assembly came from a reputable manufacturer, I'm assuming I don't need any of these wires. I just wanted to see what everyone else's opinion was. Here are the photos as reference from my truck.
