dual tank switch

can someone post the proper wiring for the dual tank dash mounted switch. I bought one with 4 post on the back. Both my sending units are grounded at the tank. (bought truck in parts so no old harness to look at. ) I assume one wire for each tank and one wire out of the switch to the gauge. Not sure about the forth wire and don't know the location of the post on the back.
