I have looked on this forum and found people changing head units. I have looked and can't find harnesses for my 2004 Mustang mach 460. I see some people have hard wired there systems. I don't want to do that but if thats my only option then so be it. I will T tap them. Can anyone tell me the wiring sequence, colors that I have to tap. I have looked on the internet and at all the stores around here. I have bought several and taken them back because the don't fit my 2004. Your help is greatly needed.
