    So i dont want to do anything fancy like you, which is yours is very cool by the way, but anyway. I want to do something like this-
    and for my car i found this- (yes its a '98 minivan)
    is it the starter wire that i put the switch into? if you could repy that would be great!

    I might be off base here, but were you running the relay to control a switch inline for the starter motor? Starter motors draw some serious amperes, and the wiring you were hooking up did not look like it would handle the roughly 100 A required. I'm kind of surprised you didn't damage any of the components in your RFID switch set up even using it once. There are other "checks" your car has built in that will prevent it from starting that you could exploit in the same manner that draw far more manageable amounts of current.

    Many manual transmission cars have a "clutch switch" that requires the clutch be fully depressed to start the vehicle, and in my car, the ignition lock cylinder needs to be in the "unlock" position to start the car, otherwise, you'd just crank and crank until the battery went dead, because it disables the fuel system
