    Low oil pressure light and ignition cutoff safety switch

    I am sure this has been brought up on here before, but need to ask one more time.. I would like to have a low oil pressure light as well as low oil pressure safety cutoff for ignition and was wondering if anyone has recommendation as to what switch and a diagram if possible of setup.
    This is for drag race application.
    Thanks in advance..

    Here are a couple links that should help. Save the diagram to "Paint brush" or similar program and resize it and print it out. The other link is for a 12 Lb switch. The momentary switch is for easier starting. I would leave out the oil pressure switch that follows the fuel pressure switch.

    Thanks RacingJunkie for the reply... Is there a three connection type pressure switch on the market that will illuminate the idiot light with no or low pressure and an ignition cut out if falls around 15 PSI? Asking a lot but before I plumb in and wire two separate switches, just want to do some homework...
    Thanks..

    You could wire it to your ignition with a relay.
