I am terribly disappointed, the harness doesn't have a blank slot next to it and it is no longer white plastic. There are two blank ones on the bottom though. Manufacturing date on this is March 2010. The harness is black plastic, smooth (so nothing to trim with a razor blade) and there is something that looks completely different from all the pics here and web videos on youtube.

Your looking at the wrong harness.

Sorry, there is no blank on the underside of the harness. You were right, that was the factory adapter first pics. These are from the X920 harness.

Your still looking at the wrong harness. The mute wire is on the AV harness.

The A/V harness is white and has the RCA connectors, etc coming out of it. If you didn't get one of those with your unit you have bigger problems than the bypass

OK, now I see. It is the same. I didn't understand. Thanks for your help.
