I've got a 2002 Silverado, no Onstar. I'm getting ready to install an aftermarket stereo. When the OEM "theft deterrent system" is armed a small red LED, located in the stereo by the volume ****, flashes. When I pull that deck out, my theft deterring flashing LED will be gone. I'm wondering about replacing it by wiring up a nice big aftermarket alarm LED, which I can install prominently in the dash. Thus, making my simple stock system look like I've got a fancy aftermarket alarm.

Can I do this without screwing up something in the OEM alarm system?

Is it as simple as I think it is... just find the correct wire in the harness and hook up an alarm LED?

Anybody know which wires in the harness power this LED? Guess I can figure it out in a few minutes poking around with a meter.

The little blinking light has nothing to do with your factory alarm. It is to do with the theftlock part of the radio. Removing the radio will have no adverse effects on the CTD(Content Theft Deterrent).

Thanks, now I understand what all those posts about unlock codes for stereo decks are about. Things have changed in the last few years... but I am NOT too old to adapt and figure them out!
