Problem: I recently had an alarm installed and the "AUTO" function does not shut off my lights after leaving the car and arming it. It stays on for good.

Search Results: So I found out from searching that, I need to send a NEG signal from the alarm to the driver's side door ECU telling it that I have left the car.

Question: Now, problem is, I've tried the red/white wire to no avail. I am using a relay since the signal from the alarm is only 200mA. Which wire is the correct one that I am supposed to tap into? My search went to a dead end here. Can someone chime in? Thanks
