How to Create a Ground While Armed?

I have Alarm with out Ground-While-Armed. I want to add DEI 516U to my alarm and need to connect the Ground-While-Armed. How to Create a Ground-While-Armed? My car is Honda Accord 09.

What alarm do you have? Does your alarm have door lock/unlock outputs? Do you have a manual for this alarm? the12volt • Support the12volt.com

I Bought my alarm from china and doesn't have a GWA. Yes have the lock/unlock output. The alarm fratures remote start/stop , push button start/stop and pke (passive keyless entry)

You could wire relays to create a latch when disarmed/unlocked that would open one relay's normally closed terminals that would supply a ground when the alarm is armed/locked. When disarmed/unlocked the normally closed contacts would open. Wiring the relays (latch) to only energize while disarmed would prevent any additional drain on the vehicle's battery while the alarm is armed. I can draw this up, but would like more information about your alarm. Are the door lock outputs from your alarm negative or positive outputs? Can you upload the manual for your alarm or take photos of it and post them here? the12volt • Support the12volt.com

Will do. I'll take photo shortly. Thanks for reply The door lock has -/+ output. I used - neg door lock/unlock

Check the 2 wires that go to the LED. 1 of those may be ground when armed.

doesn't had LED

A dual coil latching relay (such as this.. http://www./itm/Latching-Relay-Dual-Coil-12-Volt-/121913101427?hash=item1c62964c73:g:NJMAAMXQTM1R7dO3 ) connected to the door lock outputs would provide a ground while armed signal. The relay has two coils (set and reset). Set coil to lock output, reset to unlock output. The contacts of the relay wired accordingly.

The Link doesn't work. Do you have the Diagram? Thanks for reply.
