I have a dei rattler and the siren isnt as loud as i would like it to be. is there a way to tie my car horn into the alarm so that it beeps when armed/disarmed and also when triggered? will I need a 5 pin relay? how do I go about hooking this up?

Trying cleaning the grounding point of your siren first. Buy a new siren, cost $10-20, a lot less work and better result.

Run a relay and you can put as many siren as your heart desire. If your alarm unit has a horn wire you can connect that directly to the car horn wire.

don't conected direct to the horn because the brain send 12v constat, you need to do a relay and flasher for horn

87positive or negative (depends in the car horn some needs positive some needs negative)

30goes to flasher and from flasher to horn wire
