hey guys...I have a question!! I have a digital 2 1/16 tach and need to know which wire out of the pcm to tap into...can anyone help me out or send me a diagram???
There is no tappable tach signal on these trucks. You need a tach adapter, which taps the cam sensor and converts you a proper tach signal. We've got them, if you need one, they are on the site.
