Car Alarm sensor location?

[Supra5MGTE]

got an alarm for our MK3. Has this "shock" sensor... says it's a basically motion/shock detector. I'm not sure where to mount the shock sensor? Ideally you'd want it mounted where you're dome light is, but we have a targa... Anyone else have one of these sensors mounted in there car? if so, where?

I have a shock sensor.
I mounted it on the passenger side fire wall. If you mount it to the side of the car, you'll get a lot of false alarms. I put it on the passenger side to keep it away from drive by traffic vibration. You should also get a very good one. The cheaper ones don't adjust too good. You either get no vibration sensing or too much.
The heat doesn't seem to bother it.

Ah, ok. thanks for the input. I got a Commando alarm system. Seems to be pretty good quality so far.
