Good to know!One time I forgot to plug that in and it still lit up. The light blue wire, if on the Accord, is called the K-line (coming from MICU). The green line is called SCTY-, also coming from MICU. I know the 8th gen Civic also has a K-line and SCTY-wire on the 17-pin plug. These two wires have exact same colors on the cars mentioned, even the 8th gen Civic uses a different plug. However I am not sure what they are though. Anyway I've heard that a K-line has to do with onboard diagnostics or something like that.
On the Scoshe harness the blue wire is the remote wire for stock amp (no idea why it's there). The 24-pin car only comes with +12V, ground, ACC, and 2 other lines, plus 4 pairs of speaker wires. No other wires are being used. You need to flip the Scosche harness upside down (connector facing away from you) to be able to correctly compare to my picture.
Fragmented brainwaves about radiowaves, without guidance...Anyway I think now you can follow this:

Refer to the picture, back row, left to right:
1-White=+12V
2-Light Green=Front Left +
3-Pink=Front Left -
6-Grey=Front Right +
7-Brown/Red=Front Right -
11-Purple=ACC
Refer to the picture, front row, left to right:
13-Black=Ground
14-Yellow=Rear Left +
15-Brown=Rear Left -
18-Blue=Rear Right +
19-Orange=Rear Right -
The green and blue I have no idea. And I have yet to find out where the Illumination wire is. May be taping into hazard switch is the easiest.
On the non-navi units the 20-pin connector is brown. It is the "- - Handfree, B-CAN for the Midi, duet, and the aux jack" that I mentioned.For illumination, it's either in the 20-pin plug or coming from iMID. It should be a grey wire if it's on the 20-pin.
