    Very good info. Had one slight problem with right front speaker (+). Diagram above indicates color to be Red/Green, but it was actually Red/Gray wire. It took me an hour by trial and error to find the last wire match. Everything worked as stated. This site SAVED me.

    Anyone know what to do when your constant 12V looks good and your switched is reading close to gnd (0.2V)?

    Mike, if you want to use another switched source, run a wire to the steering column and tap the yellow wire in the ignition switch harness. Hope this helps. Good luck with your 2003 Honda Odyssey stereo installation.
