Wiring ignition to cigarette lighter?

[svgnewbie]

Not sure if this is in the right group, but has anyone here every used there cigarette lighter or other button to start your ignition? Think it my be kinda cool to do it, plus added security factor. seen it done on a bmw, but couldn't get the details on it.

You could wire the igniton to the lighter and press the lighter in to complete the circuit but you would have to start the car before the lighter pops out not a bad idea just doing it is a different story though.

There is a kit that replaces the cigarette lighter unit with a red push button for the starter. Is this what you are thinking about ?

a ground killswitch might be better....uncle has it on his jeep and its cool to know that no one can jump ur ignition or anything

You might have to upgrade the wiring to the cigarette lighter to handle the current to the starter--not sure.

Also, you need to make sure you can pull the lighter back out once the car starts so your starter engine doesn't keep cranking. AND you'd need to wire in a relay or switch at the back of the lighter cavity that would keep power to the car after the car starts, like it normally works, and also you need a way to switch the power off once you turn the car off.

Normally, the only circuits that are "on" all the time are the lights (you can turn any of the lights in the car on when the car is off). You don't want to wire the main circuits of the car to be "always on, or at least I wouldn't .

It is also potentially a safety issue if unknowing people are in the car and start messing with the cigarette lighter. Say some young kids are in front of your car and someone who doesn't know better shoves the cigarette lighter in and the car runs the kids over.

So you'd need to combine the circuit with the safety switch on the clutch (for manual trannies) or the brake (for auto trannies) for this to be relatively safe.

sounds like an interesting idea though, keep us updated if you go ahead with it.

what you could do is leave the ignition switch connected at the "on" position and use the cig lighter as the "ignition" switch to the starter. That way you'd start the car by putting the key to "on" (but the intermediate "start" positionwould have no effect) and then start the ignition by pressing in the cigarette lighter, then pulling it out as soon as the engine turns over.

All you'd have to do is cut the wires to the starter circuit and reroute them to the cigarette lighter, bypassing the cigarette lighter heater connection somehow--which is another question altogether--do you need to modify the cigarette lighter itself? -- in that case. Sounds pretty easy.

I had a push button start in my CB. Had to flip one of those covered switches to complete the circuit before pushing the button. Had it mounted in front of the shifter. It took my friends a while to start her

I've seen it done on a manual car, not sure how to do it on an automatic, cause the guy wired it from the clutch, so if you do know how can you post the details, it would be greatly appreciate
