Back about 6 months ago I was replacing the radio in my 2010 F-250 6.0PS FX4 with a nice Alpine unit and couldn't find a chart or listing for the color codes for the harness. I purchased a harness with the unit but it didn't come with the break out for what wire connected to what on the new radio harness.

After some research I finally found it. I think this would be helpful for any of the other members that might be looking for the color codes of the radio harness. I think this is applicable to 2006-2013 F-250/F-350s.
