Hey i picked up a 03 cavalier with an unknown alarm system installed in it. It doesnt function correctly. The model number is MDC:342 K109 i have googled for about 30 minutes and yet to find anything not even the company who makes it. If anyone has any info on it please let me know thanks!!!

Its probably some cheap ebay one. I'd take it out and get a new one.

if you want wiring info though (not necessarily related to that specific alarm) check out The 12 Volt
