I'm getting the push button start from AmericanMuscle and it make me think a little... My girlfriend lives in a not so trustworthy part of St Paul mn, and come spring time and I have to part my car outside I want to run a disabling switch so she can't be stolen... My original thought was to run a switch off the new push button, but not sure if that will accomplish what I think... I can't really decide where to run the switch from... Started? Battery? Fuel pump relay? I had a toggle switch on the fuel pump relay on my old truck....
