Oil pressure gauge with single terminal warning light?
You can get the keyed 12v pos from the cir board or other under dash sources
If your cir board looks like this...
If not post a photo of the cir board.
All 3 points are 12v switched (12v when key is in run or ACC)
The arrow "12v pin" is the 12v input to the cir board. If you tap into that wire that will provide the switched 12v you need to feed your oil pressure light.
