Hi all, I just bought a 71 C10 SWB. The truck came with aftermarket gauges, I picked up an original cluster from Ebay and need help with the Water Temp gauge. It has 4 prongs on the back, what is supposed to hook to what, I know one should be ground and one should be from the line from the head on the engine, what are the other two prongs for?

Also if looking at the cluster turned over what are each prong supposed to be.
Am I right with at least the first two?

Example

Left prong: Line from engine
Right Prong: Ground
Top prong: ?
Bottom prong:?

Please help!

Thanks
Matt
