I am trying to wire in my sunroof to make it work. I have a 2006 wrx wiring harness in my car, and it didn't come with a sunroof, so there is no direct wire to connect the existing rs sunroof wire to. I got the map light and the room light working fine, but i can't figure out a good location to wire the sunroof to. I imagine it would need to be some sort of constant power source or something, but then again i am not sure. what do i do to make that work?
