I was wondering if I could hook up my RS2 to my horn, so that when the alarm sounds it also honks the horn. But in a beep- beep fashion, not just a constant blast. Thanks

You should be able to get a relay and reverse the polarity of the horn sense a lot of horns are negative trigger.

You could use two relays to make a horn honk circuit. Relay 1: 85 +siren output from alarm, 86 ground, 30 ground, 87 output to relay 2. Relay 2: 85 +parking light output from alarm, 86 ground, 30 input from relay 1, 87 output to car's -trigger horn wire.

Ooh goodness.
86 +siren output
85 ground
30 12v
87 to one pole of two pole flasher
other pole to positive horn

Yes and no. Modern day horns are negative in the vehicle but positive under the hood while most all older vehicles are positive both in and out.

Thanks, I think that is the perfect solution. I feel like a dumb ass now, flasher, DUHHH. LOL Thanks again

The only modification that I had to do to this is to put the flasher before the relay, that way there isn't a lot of amps going through the flasher and when I arm and disarm the alarm the horn chirps, otherwise it doesn't respond fast enough. Thanks for the help!!!

with the clifford alarms, as long as your horn is (-), all you have to do is connect the BROWN / black wire to your horn wire. It will honk your horn the way you want. It will not give you a steady blast.

Do it right the first time

Raydawg, I don't have any brown with black stripe from the alarm. But what I did do was take an electronic flasher, connect that under the hood to the siren+. Then from the load side of the flasher to the relay 86, then 85 ground, 30 to 12v+, and 87 to the positive horn wire(connector is right next to siren). And it works perfectly, short honk when arm, two when disarm, and honk-honk-honk when alarm is activated. Though if I were to do it all again, I would have taken the H1/10 brown right from the alarm, and used the relay in a negative fashion to the black negative horn wire that way I could have everything up under the dash instead of in the engine compartment. Which if I am feeling frisky I might just redo it so to be more professional, though I hate soldering while standing on my head. posted_image

I was messing around under there yesterday and took one of my aux outputs so that when I push the trunk release button it honks my horn. Fun messing with people walking down the street. Thanks for everyones help and hopefully I will be adding some more features in the future.
