Hi
i have a 99 ex civic with "Bosch vs-s001 Vehicle Security System type vim171". I want to connect another bigger siren to my alarm, to do so i need to find the wire that give me power+ when then the alarm is triggerd only (not when i turn on and off the alarm)

on the alarm itself (behind the inside left dash) i have 2 connectors one of the with 20 pins and one with 16 pins, all the wires are black.

does anyone have this alarm wiring circit or someone know how to fo this kind of thing?

 

Splice the power and ground into the other sirens wires, or
You can just splice the pos and then ground the siren where you please

 

see i dont have a problem with the power source , i need the AUX Output command that will triger the secondery siren when the alarm is trigerd.

i also attach some pic's of the alarm in case someone seen it

 

dose anyone know where i can find help in this topic

 

i'm desperate

 

 

anyone?

 

That's what you have to do. The primary horn has 2 wires... tap the secondary wiring into the primary wiring. Unless you have a option for a secondary horn. then the above is void.

I have installed a high security alarm on a car and I had ran 5 horns. 1 mounted under the battery tray, one in the front and back bumper (you'd be surprised at the amount of space behind the bumper covers), and then 2 in the interior. One in the dash, and the second behind the plastics in the rear by a speaker grill. The sound of that car when the alarm was triggered was ear piercing. It was great.

 

op, did you not even read my post?
I told you exactly how to do it.

When you tap the positive wire on the old siren it will trigger the new one, as long as its grounded properly, You can call that your aux output command.
Which i doubt that alarm even has one.
