After installing the sensor, I attempted to jack up the vehicle. It sounded the full alarm before a wheel lifted from the ground. Great addition to my Python 872 security system.

This sensor was very simple to install. The color coded wires make this fool-proof. After mounting, I tried to "steal" my own wheels, and set the alarm off long before I could jack up the car high enough to remove any wheel. I'm very happy to have this sensor.Read Best Reviews of Install Essentials 507M Tilt Sensor Here
Bought this sensor and a Viper 350 responder alarm, installed carefully on my car, always metering every line at the car's harness that goes to the alarm. (I've seek on Internet to get a guide on my specific cars harness) I installed the sensor as the manual states: "facing upward" it is recomended to be installed on the floor because it needs to be horizontal mounted, but instead I used the 2 sided tape and sticked on a plane surface near to the radio. After the full installation, I make a test, arm the alarm and beging raising the car with it jack... surprise!! it's true! it detects tilting before wheel get in the air!! wow! it's a great addition to the alarm an therefore a great peace of mind if you have great wheels & rims!!!It isn't necesary to get a DEI alarm to use this sensor, it use 3 wires: blue, orange, red. the blue goes conected to any 'instant trigger' of your alarm, the red to constant positive(+), and the orange connected to a Ground-when-armed (-) wire. If your alarm doesn't have it, make it through the use of a universal relay.
The relays have these numbers marked on it:
* Connect pin 85 to Ground(-) & pin 86 to ignition wire(+)
(check polarity on relay if it have a diode) these are the coil's pins.
* Conect pin 30 to ground(-) & conect orange (from sensor) to pin 87a
There's a lot of ways of make a ground-when-armed(-) line. All it have to do it's cut the line orange(-) when you put your keys on ignition. The sensor will reset to the last position plane when you turn the engine off from ignition switch, then this is when the sensor will be on.Works great. Only problem is that I had to put in a toggle switch to bypass when I park at work. something would trigger the sensor about 30 seconds after arming the alarm. The toggle fixed the problem.
