Use those as reference for running the wires for the switch.I think you might have to cut up the HVAC a little to hide a switch behind the A/C button. You could also try using the existing wiring in the a/c button instead of fitting another button behind it. Good Idea of putting it there tho.

If you can make the Nissan an actual buttona "push on/push off" toggle switch maybe? idk that would be neat, clean and hidden in plain sight.

I have and extra Climate panel, I might see how difficult it would be to remove it and it still look stock like it does nothing.

Wasn't there a guy who said he install things like this and set up some clients car with RF id to turn on the fuel pump?

one way is an RF ID relay from http://www.2wheeltouring.net/2...d.htm even if it's for a motorcycle, those things are out there. I know some new cars have them built into the keys but after market i mean.My only worry would be it losing connection halfway through a drift or something and effin things up.

ok so u guys go the whole idea thing but, i want it for the starter so i can just press it once and it turns off after that. Since i worked on a jeep once with it like that i had to press the a/c button to turn it on. SO in other words if u guys can help me out with finding the starter wires or something out that would be great and major help. Thank you

groovy idea

dont tell people on the internets

you can cut one of the wires from the ignition here. (don't know which is the actual ignition lead) and then extend the wire to the climate control unit where the switch would be at.Press the button and turn the key. ORextend the wire to that RFID relay and mount the relay to the inner wall of the dash nest to the CCU or in behind the shroud where the vent is right under the cluster. so as long as you have the RFID fob attached to your key ring the car will start. AND if it loses connection while driving it won't matter, it would just be connecting the two end of the same wire. Hell you can start the car and put the fob in you pocket after that

well yeah... somewhere, probably hundreds of ways that you could probably setup a kills switch.

Interestingly enough, that nissan piece just pops out. Just shave down the sides, set in a small push button whatever and glue the piece back on top?

Btw you know that with a starter kill switch, you can still push start the car right?

Good luck with your project

I have a switch for my fuel pump and for my clutch, but they are open in plain sight.

I really like your idea with using the cigarette lighter as a switch, but I would think you would have to make it so that it does not get hot(?). This really makes me want to hide my switches now and put my OEM buttons back in

I understand that, but when you push the cigarette lighter in it heats up. That's why it's a cigarette lighter. Maybe you are thinking differently about this than the way I took it?

It might be worth it to try finding something similar to a cig lighter, so that you have the only 'key'. In the event someone sees you do it, or a friend tells a friend what you did... you know what I mean.

You can get as fancy as you want.

Example, and this one would be easy.

Key on, but before it would crank:

1)Parking lights have to be on2)and or the radio has to be on(if you have a aftermarket radio)3)and or the foot brake has to be pushed in4)and or the E-brake has to be on5)and or the door has to be open6)and or left or right turn signal has to be on

...... we can go on all day long. All of these would be very simple and only require a single relay. The relay would keep the starter wire open until you activated it with one of these scenarios. If you use multiple scenarios, then you would need multiple relays. I also have paper thin momentary switches that can be mounted under material etc.
