07 Sierra Classic
Viper 791xv remote start.

I've got the horn honk output wired in, it's been working fine up until a few days ago. Alarm got set off by me bumping it in the driveway. Horn did not honk on full shock trigger, panic, or door trigger.

What do I need to look for? I have verified all wiring is correct.

My deepest thanks for any help

Does the horn work? Are you using a relay?

Check your connection. Get your meter out and check the vipers output.

No relay. Local shops advised to wire the alarm trigger to the horn wire.

Horn does work.

Thanks for the reply.
