I have two wires from sensor.
I wanted to make a engine kill switch, if oil pressure drops say below 5psi it makes a open circuit and cuts power to ECU, I know start up will take longer as engine is cranking and ECU is off until correct oil pressure builds and ECU gets power and starts.
I dont have the crank collar dont but i dont want to completely destroy a RB is it does go.
