okie08vette Posted November 27, 2010 Report Share Posted November 27, 2010 The auto dimming does not work on my 120, installed on a 2008 corvette. It appears the orange wire is the dimming circuit wire do I need to provided a constant 12 volts on this wire or does it need to be tapped into a wire that is hot only when the headlights are on?

It needs + voltage when the lights are on only. BTW, this isn't a dimmer circuit, like your dash lights. It changes between the daytime and night-time setings. They can be customized by holding the Mode button for a few seconds. Quote Link to post Share on other sites

Thanks and yes I understand about it just changes the settings between day and night right now all I get is the option for day time, I need to connect the orange wire to a different source, now I will try and find that source on my car.

Thanks I ended up running the AVIC wire back to my tail light housing. Although there may have been a closer place to tap, it would have been a pain to find buried in some wiring harness under the dash, and the back of the taillight was a sure thing. Just make sure it isn't the brake light or turn-signal. Quote Link to post Share on other sites
okie08vette Posted December 6, 2010 Author Report Share Posted December 6, 2010 As I was told the gray wire at the traction control button on the center console work's great on the C^ corvette. I hooked the orange wire there and the dimming works great. Thanks for all a the help. Quote Link to post Share on other sites
