What's this switch do?

[freefall]

Anybody seen one of these (bottom right switch)? Dealer told me it turns off "exciter" speakers but does not. Then they told me it was the sub switch when they put in the A-Trac switch but obviously it is not.

Also, adding rear speakers and possibly a sub. I saw the good threads about wiring for the rear speakers. But, is the sub wire harness already plugged into the back of my non-FJammer unit or will I need to wire it up after I install the sub-switch? Probably won't use the factory sub, just curious.

Thanks

the switch defeats the "radar" for detecting intrusion by thieves, in case you want to lock your car and move around inside.

Thanks! That's kinda cool I guess.

the intrusion radar can be triggered by a cellphone left in the car, or an animal.

Or by 2 people moving around in excitedly.

I can see now why he thought it turned off the exciters in the ceiling. It is called the mystery switch 'round here. Where you at in Texas Freefall?
