Door Lock/Alarm Question??
 

Hi All,

I just picked up a new (leftover) '04 3 hatch, and wonder if anyone has any idea where I can get an add-on component to automatically lock the doors when the car is started? Here's the one problem; it has to be able to plug into the wiring, as I'm not about to cut wiring on a new car.
I've had issues with wiring being damaged by ham-fisted alarm experts, and don't wanna go down that road again. Thanks for any advice!
