hey everyone, im new to the forum , i just have a quick question. ive tried searching but no luck, i recently but a 2004 hch and as i was detailing the interior i found this toggle switch hanging from under the dash near the hood latch release. does anybody know what its for?

 

here's a picture of the switch in question

 

that's not from the factory........

 

i figured that much, i was wondering if anyone might have an idea of what it could possibly be for seems like a pro install, Ive tried turning it off to see if it was a kill switch but the car still turned on so i'm clueless lol looking at my first post I can see were it might have sounded as if i thought it was factory
thanks

 

what it could possibly be for seems like a pro install.

that's not a pro install............lol

 

ok ....... i'm asking for help in trying to figure out what its for, i don't need any meaningless comments ....... thanks

 

you can test or replace that switch. it may be a kill switch that has failed.
you need to take those panels off, take the tape off and trace the wires.
do some investigative work yourself...........

 

That's really strange. I installed a toggle switch like that (but cleaner) in my wife's Buick Enclave to 'trick' the stock NAV unit into thinking the car was stopped so we could enter a destination while the car was moving. I cut the VSS (Vehicle Speed Sensor) wire, and placed a switch in between. I don't think that's the case here.

Years and Years ago my wife (then girl friend) had a '76 Toyota Celica that had an intermittent ignition problem so I permanently hot wired it to a push switch under the dash. If the car didn't start with the key, she could simple push the button under the dash and it would go. As long as the key was in the ignition to unlock the steering, everything was fine. Cars were so much simpler back then.

 

It is probably something to do with FAS for hypermiling. Probably stops the ICE when in neutral? Only a guess. What does it do in on or off? Have you traced the wires? Maybe it is a anti theft switch? H
