where to mount shock sensor

Initially I had used a bolt attached to a huge pipe/frame of the car behind the glove compartment (the shock sensor had a screw hole so i didn't need wiretie or double sided tape).  Though I have yet to adjust the sensitivity (issues with romotes) it doesn't seem to go off much.  I was thinking maybe my mounting location was not good, like i said, it's screwed tight to the frame.  Maybe when i jar the car the frame doesn't move enough to trip the sensor.  Had I mounted it to say a bunch of wires, the sensor would move more when the car was jarred (the wires can move more freely then the actual steel frame....)

try mounting it to the front fender under the hood , the fender will have enough vibration to set it offdogsalan1

typical mounting location is on the steering column. When the car is jarred, the suspension moves just slightly, moving the steering which then vibrates the steering column.
