What up my fellow nissan enthuiasts, I'm new to this forum although I have been here before to read stuff. I hope this community will help in current and future projects, as of now I have a question or lloking for some input. I want to run a "killswitch" or immobilizer type of switch, I don't know how to really call it. I want to be able to power the ecu with that button after turning the switch. I know I can install an anftermarket button or toggle switch and place it anywhere I want but I kind of rather use an OEM button off the dash that I no longer use, maybe that will help in case someone actually tries to steal my car and can't get it to start. They'll be looking for something a little more obvious, like a aftermarket button or switch. So I was thinking wither the cruise control button or the defrost button circuit. Has anyone ever done this or have an idea of how I can go about it? I know I can locate the relay that powers those circuits once you push the button and just re-route the voltage to the ecu voltage. Any help would be much appreciated.
