How to Create a Ground While Armed?

There are 3 pins on the Shock sensor connector. Check them.

Yes the shock sensor has the 3 pin.

The Manual for DEI 516U

Did you check the 3 pins of the shock sensor connector?

The green wire from dei 516u I connected to one of the 3pin shock sensor.

Someone? Pls! Help

Here's a diagram I just created for you. Please read the second paragraph in my description. https://www.the12volt.com/relays/relaydiagram69.html Connect your negative unlock output to the light blue wire and connect your negative lock ouput to the green wire, then use the orange wire as your "ground when armed" output. the12volt • Support the12volt.com

Thanks. I appreciate it. These r right to go on the wiring? Light blue go to - neg. Unlock Green go to - neg. Lock Orange go to ground-while-armed DEI 516U or any has the GWA? Voilet go to ??? Or go to GWA ?

Correct. Light blue to negative unlock from alarm, green to negative lock from alarm, and orange is your "Ground while armed" output. The violet wire doesn't need to be connected to anything, but can be used if you need a ground while unlocked/disarmed. When you first wire this up, the orange wire will provide ground until you disarm your alarm, even if you have not yet armed it. After the first cycle, it should perform as you want. The violet provides a ground while latched. If you were to connect unlock to green and lock to blue, then this would be your ground while armed, but this would also pull more current from the battery while the alarm is armed, hence recommending wiring the way I stated above ;) the12volt • Support the12volt.com
