I am wiring up a remote start system for a set of L.E.D's on my car. I am setting up the trunk unlatch button on my remote as the trigger to the relay. It is a (-) output but it isn't a constant power. So I am guessing I need some sort of a latching device, or relay, or even both to keep the power constant once it has beeen switched. I have no idea how to do this or get this effect, and Ive been working on it for a while. Any help would GREATLY be appreciated. And even an idea of where to find parts would help a lot. Thanks.
