I've installed a Lynx 2000 in an '02 Silverado 1500HD and attached the alarm/autostart negative pulse disarm wire to the BCM (violet plug / Lt. Green wire), but the factory alarm doesnt disarm when armed by locking the doors with the factory remote or by pressing the door lock button. I've checked the connections and verified that the Lynx is sending the negative pulse, but no disarm.

Any ideas?

Thanks

What is the best way to test it. I've put a DMM on it and you can see it pulse, but it still doesnt disarm the factory. Is it possible the factory is on a different wire then the lt. green? Anyone else had this on an '02 Silverado 1500HD?

I guess I can test and make sure that the factory unlock is pulsing the same wire, or is there a better way to check it?
