My oil pressure control relay that plugged into the fuse panel died a wet, rusty death long ago. I have an oil pressure gauge, but I don't look at it as often as I probably should. But there's an idiot light already in the dash. If I jumper (in the relay panel) the idiot light to the sender that switches 'on' when oil pressure drops, would that work? Would it light up if the oil pressure dropped?

I'm pretty sure the oil light has positive on one side and when the switch gets grounded it lights up.
I'm not sure which plugs you would jumper to bypass the relay.
Bound to be one coming from the switch and one going to the buzzer.
