RonS Posted November 6, 2010 Report Share Posted November 6, 2010 which wire is the dimmer wire on the 120 wiring harness? is there a wiring diagram somewhere that lists them all? There is no "dimmer" wire, but connect the Orange/White wire to a circuit that is +12v when your lights are ON. This controls the day/night display on the HU. If you have Daytime Running Lights enabled, this can be a problem on some cars. I had to disable mine cause the HU always thought it was night. As far as the rest, why don't you check your Installation Manual, or download it from the Pioneer web-site. And as homework, make a list of all the other wires. Then post it here.

rgarjr Posted November 6, 2010 Report Share Posted November 6, 2010 some people refer to the Illumination wire as the dimmer. Quote Link to post Share on other sites
RonS Posted November 6, 2010 Report Share Posted November 6, 2010 some people refer to the Illumination wire as the dimmer. Yes, and that is a point of confusion, especially when they connect it to the dash light dimmer circuit. You can't "dim" the AVIC along with your dash/instruments. You can only toggle between the day and night settings (which can be customized by holding the Mode button). Quote Link to post Share on other sites
panteralkn Posted November 8, 2010 Author Report Share Posted November 8, 2010 I've been looking for a wiring diagram of the main connector. Not all the wires are labeled - it is not on the CD that came with the HU. and thanks for the clarification - i'm not looking to dim like my dash - but to go into night mode when my lights are on.
