Hi guys, got a new alpine head unit today (CDA-137EBT) and one of the wires i need to connect says to join it to the 'instrument cluster illumination lead'. My old head unit did not have this so there is no previous connection there and I havent got a clue what wire to use, I can't find anything in the workshop manuals about this illumination lead, does it exist on the CC GSR? I'm assuming it is used to dim the head unit when you turn on your headlights, so it's not really a big fuss if I can't connect it. Thanks for the help
