Step 1
We recommend having a professional alarm shop install this item for you. You do risk damaging your car or alarm if you decide to install it yourself. But if you insist, here’s how in layman’s term.
1st. Some alarms have an extra sensor input. Most car alarms don’t. If your car alarm has an extra sensor input wire, use it. If not, then you’ll need to locate on the alarm. Locate the shock sensor on the alarm. The shock sensor will have from 3 to 4 wires coming from the car alarm brain. Usually its black, red, blue, and, green.
Splice the red wire of the tilt sensor to the red wire of the shock sensor.
(If you’re using the extra sensor input wire, then connect the red wire of the tilt sensor to 12 volt constant positive) -
Step 2
Splice the black wire of the tilt sensor to the black wire of the shock sensor
(If you’re using the extra sensor input wire, then connect the black wire of the tilt sensor to a negative when armed wire of the car alarm. This negative when armed wire is usually colored orange. If your car alarm does not have this wire, then you can connect it to constant ground. By doing so, the tilt sensor will always be on. There will be a very small battery drain but it shouldn’t be too bad.) -
Step 3
Connect the blue wire from the tilt sensor and connect it to the blue wire of the shock sensor. Be sure to use a diode between this connection to prevent feedback that will cause false alarms. Note* I have hooked the tilt sensor up many times without a diode and it still worked fine with no false alarms.
