central locking snag

[casamensa]

After fiddling with my car stereo of my 190e the central locking stopped working, ocassionaly it will function with ignition on.  Looking  behind the stereo i could see a crash sensor which i disconnected, obviously this didnt cure the fault but i suspect thats where the fault lies, does any have any ideas or usefull shematics?

Thanks

i discovered something while changing the alarm (and thus c/l interface). On a 190 you can lock all the doors from the inside by locking the driver's door or the front passenger door, except when the ignition is on when you can only do it from the driver's door. (So the passenger can't lock everyone in, I guess). Thus there is some slightly-more-complicated-than-usual wiring going on there. Can't be any more help tho - sorry!
