    The one that causes this and runs the gauge is on the lower drivers side by the oil filter housing. It has contacts that melt inside and give you erratic or no oil pressure readings. The one on the top that the other guy was talking about is not the right one. That's the fuel pump/oil pressure switch that shuts off the fuel pump in case you have no oil pressure so you don't burn up your engine.

    look along the outer sides of the block...there should be either senders or switches already threaded into the block. most engines no matter who makes them have auxiliary oil gallery plugs in the block. usually 1/8 inch pipe thread. sometimes 1/4 inch...easiest way is to find one of those plugs or senders/switches, unscrew it...if coolant comes out, you're at the wrong hole....look for wires or lines(if a mechanical guage is being used) coming off the engine block...

    Looking into the engine compartment from the driver's side it is all the way back where the engine meets the transmission (bell housing), below the rocker arm cover.
