Ok well I have done countless searches and a lot of reading. However I cant really get a straight answer so I guess ill beat the dead horse... I dont want to bypass or change anything in my mach460 system. All I want to do is add an aftermarket head unit because I need the space under my radio for my guage set-up. I have found a couple different harnesses but dont know which one is the one to use...
