Hey guys, i'm putting this system on a 03 silverado. The customer wants the factory horn to chirp on lock and unlock and obviously when the alarm is triggered. I'm using the white (-) 250 ma output of the system to a relay going to the black wire of the truck, but i'm not getting any chirps. Is there something i need to change in the programming, or is it even possible. This is how the relay is setup, and i know it's correct. 86 12v, 85 white(-) 250, 87  ground, 30 out to vehicles horn.

Thanks for any help,

Mike

Alright, i got it figured out, the white(250)ma will not chirp the factory horn on lock, and unlock, but will honk during a full trigger. That's good enough for me.

It has to be programmed to trigger the horn  on lock/unlock.
