Hi, I've got an Alpine ida-x100 installed in my 06 jeep grand Cherokee. The deck has a dimmer feature which dims the deck when the headlights come on. When I got the deck installed they didnt connect the wire which allows this feature to work. Does anyone know which wire I need to tap into in order for this to work? The wire coming from the deck is orange, and from what ive gathered the wire i need to find is called the dash or headlight "illumination" or "dimmer" wire.. I would assume this wire would also be orange but there are three wiring bundles behind the stereo and im not even sure where to start looking. Thanks for your help..
