Ok, I finally decided to get my alarm installed by a pro after trying and then giving up. When I stopped, I left the shock sensor on the firewall. the guy didnt see it and didnt hook it up. so today, i found the wire that needed to be plugged into the sensor and plugged it in. i locked the car and tried bouncing the car around and I didnt get any response. it seems like the sensor isnt working. is there a "proper" way to setup the sensor now that the alarm is already hooked up without it?
