Alright, I have swapped my gauges and gotten everything working in my 85 xcab/4wd truck. Swapped in the full gauge setup with speedo, tach, voltmeter, etc. I knew about the oil pressure switch situation so until I had the correct sending unit, I left the wire unplugged. I purchased the oil pressure sending unit from Napa. The new sending unit has the nub on the end where the wire slides on, but it has a small tab on the side as well where something else should attach. I get nothing when hooking up the wire to either of these connectors on the sending unit. Is there another wire that should go to the extra connector? Or what gives? Is my oil pressure gauge bad? I would think that an oil pressure sending unit would need some sort of power as it is not mechanical so should there be a power lead going to the extra connector?
