I wanted to start a thread with all of the info we have on the harnesses adapters and such for Mach460 head unit replacement. Each picture kinda explains itself. Each one of these are from crutchfield. Basically if you had each one of these (not all of them are needed but nice to have for the intall) then you should have no problems installed an Aftermarket head unit in your Mach460 system. SORRY UPGRADING FORUMS, ATTACHMENT WAS ERASED, YOU NEED TO REUPLOAD!
