Alarm night rider light, where to tap into?

[Jstforkicks247]

Well I purchased one of those blue led night rider looking lights, I am trying to figure out where to tap into. It has two wires only(power and groud obviously). Does anyone know where to tap into to where it will only go on only when the car is off. Either if there is a ground or power wire that activates when the car is off, please and thanks!

Ok I found the power to tap into, just need to find a ground that activates when the car is turned off, please and thanks again!

If your still looking for that ground. Is your alarm aftermarket?? if so it will have a start kill which has a neg. outout when the alarm is on, thats where I wired my LED setup to.

If anything, either go to or call an audio shop that does alarms and just ask.
