Car alarm BATTERY back-up SIREN wiring HELP !

[kote_alex]

I bought a siren like this one in the video and don't know how should I wire it

(link removed)

I have a red , black, white and blue .... red and black are positive and ground and the others are Alarm Trigger + and - , I wired the red one and the white one (trigger + ) to the alarm white , and connected the ground , but I don't know where should the blue wire go (trigger - ) go .

Ooooh ! ... when I turn the key from the RED position to the Blue position it starts but it goes silent rapidly , that's because the inside battery is dead or is not charging because of the missing blue wire , am I right ?

Thanks in advance !

You may be better off contacting the manufacturer for an installation manual if you dont have one.

where did you buy it from? any numbers on the case or anything?

My guess is that alarm trigger (+) is for opening of doors etc (triggers the alarm) and alarm trigger (-) is for tone or just connected to ground? You really need to manf. details.
