shock sensor with keyless entry ??, can I ? Options

[Batman722]

my car has been hit 2 times without me knowing.

Is it possible to hook up a DEI shock sensor to my keyless entry system ? I am familiar with them, I installed one in my Jetta, I was thinking I could hook it directly to the horn/siren...? It would at least produce a chirp or something if it was hit.

Would this work ?

yea that would work..

do you know how many mA the constant negative can handle?
if it can handle alot, you can just hook up the ground of the shock sensor directly to the negative constant.. But on the safe side, i would use a relay.

have you thought about how long you want the horn to stay on for (when the shock sensor activates)?

you can even get a blinker relay to make the car horn honk in intervals.


i dunno, but there is alot that can be done.
