Customize our stock alarm system?
I was wondering if anyone on here has wired in an aftermarket shock sensor to their stock alarm? I just found a spare DEI shock sensor (exactly like the one pictured) laying in my garage and would like to wire this to my car if it’s remotely possible, then an additional siren to the shock sensor. If anyone has wire schematics of the W211 chassis, please PM me. Just some added safety I want to add to the ride.

hmm... I might be interested in a different type of a shock apparatus. How about a shock electrode inside the car that actually gives a shock back 
Seriously, I doubt you'd be able to link this to the alarm system. I'm still looking for a remote engine starter and I have been unable to find one that would work because of complications of making it work with the MB car alarm system without compromising it.

dont even bother guys... its not happening... you "could" add a seperate siren, but even that is so outrageously annoying it wouldnt be worth it unless your doing it yourself. you could isolate the signal going to the factory alarm siren, and send it in to another siren

Shock sensors are very inaccurate sensors and therefore most car manufacturers do not use them. They are more of a nuisance than anything. You can add a interior motion sensor which will detect glass breakage as well. This is a factory sensor mounted in the middle roof of the car. Also, is the factory siren not enough? If you have teleaid, you can activate that and it will notify you if there is an alarm set off.
