Any idea what this aftermarket switch does?

By popular demand, I opened up the panel. The switch connects to some green wires headed in the direction of the stereo.



I checked in the stereo manual and found this: "Light green - Used to detect the ON/OFF status of the parking brake. This lead must be connected to the power supply side of the parking brake switch."

So it's a way to make my stereo think the parking brake is on so I can scroll through my contacts list on the stereo.

 

Winning!

Don't do this you. You might not like where it leads.

If the LED is out, your battery is dead.

 

Me and 05tacomabro are both geniuses...someone should make a note of this for future history classes.

 

Lol oh shit it must be running on unicorn farts

 

It's hooked to my front porch light, stop flipping it.

 

Led light is usually a dealership or aftermarket installed alarm. It just blinks when you lock the doors. Just a guess on that though. I have a little blue one that blinks when I lock the truck. I figure it's a good deterrent for thieves.
