So I've got a question and i know there's ways to do this as I've seen people post it for sale fully lit with a12 volt gator clip setup. My lower cluster messed up, the upper gauge is fine but i need the lower replaced, i want to go to the junk yard and test then to see how many miles they have, mine failed at 176k i front tranny a 300k plus for obvious reasons, just want 1 that's close, many online don't have miles posted, does anyone know the pins that power it up?

The schematic I have for the 8th gen isn't giving me pin numbers. But, there is a white wire for battery, a brown for ignition, and then two black wires for ground.
