Remote start + siren

if i dont have a siren output but have a light flash output how  can i hookup a siren to go off when i lock/unlock doors. right now i get light flashes to display door locks/unlocks. how would i go about hooking up a standard siren to that?

Maybe some one knows but with out info on the unit and car we will have to acll Miss Cleo to fing out the answer.

hook up a siren to a relay with the parking lights isolating them so the siren only goes off when arming and disarmingThere are 10 types of people in the world, ones that understand binary and ones that dont.

Like said above. If your car/truck only needs low power neg to activate the lights then just put a diode beteen the alm and the light wire. On the alrm side of that same wire connect the siren. ONLY if the wire your are connecting to drives a relay or computer input. If it carries the power then I'd recommend 2 relays. Use the wire from the alarm to activate both relays at the same time. On relay sends power to the factory light wire, the other relay to send power to the siren...

sorry i cant believe i didnt put in the car info.... its a 1998 blazer and i have it set to give a positive pulse to activate the lights. floater could you point me to any diagrams perhaps, im not really good at knowing how to hook it up w/o diagrams... thx so far...

Is it set up with an external relay for the parking light pulses? If it's internal, it'd be harder to do, unless you have large diodes or want to get inside the alarm module.

the remote start has a white wire coming out of it that is fused 12 volts that i ran to an external relay to the parking lights wire.

Does the remote start continually flash the parking lights while the engine is running? 

Yeah, that would be kinda annoying after a while, wouldn't it- If it only flashes when doing the lock/unlock, then it'd be easy, otherwise you'll have to gate it out when it's in RS mode.

yes i believe it does, and yes that would suck quite a bit if it did that. is there any way i could hook it up to the door locks then??? thats all i want it for is so i know when my doors are locked or unlocked. i have 2 external relays for my doors which are 3 wire + pulse.
