Im installing a 5" autogauge tach with a shift light in my 1998 mustang gt. My question is what color wire do I hook the tach input up to by the computer? I was told by pep this year doesn't require a tach adapter. He was suposed to email me the diagram but I havent seen it yet. Any help is much appreciated!
