crazy setup, python 991, 95 maxima

Just connect your keypad as the diagram states, and connect the output of the switch to the keyside of the cut starter wire,  connect the input of the switch to a good twelve volts source. this way once the pad is active the onboard relay would prevent the button from cranking the starter and when you de-activate it the circuit closes allowing you to push start the car. I'm assuming the switch illuminates as there is a ground input, just ground this pin and you should be set, be sure to verify that your switch is capable of handling the current the starter wire requires to crank the engine.

i'm now understanding you! ok revised plan! connect your keypad as normal, except the constant 12volts wire this you connect to the output of your toggle switch, the input side of the switch to permanent twelve, now using the two wires that are suppose to connect to the starter wire, connect one side to a true ignition wire in the vehicle, then using a single pole double throw relay and your pushbutton, wire it like this,

pin 30- to a good twelve volt source (at least capable of supplying 40 amps)

pin 86- to the side of the unused starter wire from the keypad

pin 85- to the output of your push button, the other side of the button goes to ground.

pin 87- tap to starter wire in vehicle! and off you go!
