e=mc2 E 2006 Chevy Impala Sony CDX-GT565UP I have soldered all the correct colors together on my harness to my Sony radio. There is one wire left on the back of my Sony CD player. It is illumination, and I don't see any spot to hook it up. I want to retain illumination functionality. Do I tap into constant or accessory? Thanks. #1 · May 28, 2014 (Edited by Moderator) 2006 Chevy Impala Sony CDX-GT565UP I have soldered all the correct colors together on my harness to my Sony radio.

If you connect to either a 12v constant or 12v switched wire it will always be dim. You could put a switch in to manually dim it or tap the headlight switch if you wanted. I don't think I've ever used the illumination wire in any install ever, lol. #3 · May 28, 2014 Thanks. I thought hooking the illumination up would dim the cd player as you dimmed the dash lightsdown 0 Reply #4 · May 28, 2014 It can if your car is equipped with that function and the deck is equipped to handle that signal. Some decks just use it like a remote wire; it's either dim or full power. Some will accept a voltage range to be able to dim along with the increased voltage on the wire. It might mention this in the manual, or you might have to contact Sony to get an answer on what kind of signal the illumination wire can accept. #5 · May 28, 2014 I've either tapped into the back of the dash light dimmer circuit or cig lighter illumination circuits. Whatever is closer to the head unit. #6 · Dec 3, 2023 I have same problem but my stereo won't even turn on unless headlights are on?? What the @$#! did i do wrong? #9 · Sep 11, 2024 You hooked your main power 12v constant from your radio to one of the wires that leads to your headlight on/ off switch Go through the wires with a voltmeter and find the wire that has a constant 12 volts with everything off hook red wire to that turn key backwards go through wires again find the one that has 12 volts with the key being backwards hook your yellow to that 0 Reply #7 · Dec 3, 2023 You have the Battery Hot input to the Head Unit wired to the illumination circuit... #8 · Jan 30, 2024 My stereo won't power on unless I connect the orange illuminate wire to the red 12v. Then only powers on with my headlights. I tried to just leave the orange wire taped but wouldn't work. What else could I do? #10 · Sep 11, 2024 ive always thought it odd that more shops dont hook this up as i find it quite nice to have hooked up Insert Quotes Post Reply
