    Anyone that has access to OEM schematics can you please help. On the factory piezo there are 2 wires.. white/black that goes to ground and the other is red that gives 12v to the piezo to make it 'beep' for lock/unlock. Where in the car does that red wire connect to?? I'm guessing the factory key less entry module, but where the heck is that located??

    My piezo works fine with factory remote lock/unlock, but if I unplug and manually apply +/- to it, nothing happens! I can't figure this stupid piezo out to save my life! I've been told that this is a standard 12v +/- buzzer but it HAS to be some type of data signal because I can't trigger it manually. Please help!
