I dont think there is an analogue signal from oil pressure. I know there is a switch but havent seen a pressure transmitter, and havent seen an oil pressure reading using the GAP IID tool.
Gauges? 2 maybe three. It depends if I see a means of mounting them and how many holes it has.
I reckon one of those multi gauge pods mounted just to the left of the instrument binnacle. I dunno, thats why I'm fishing.
