Yea, another tach wiring thread. I have an autometer tach and I can't seem to get it to work. I know there is a tan/yellow wire coming from the coil that is what your supposed to hook the green wire coming out of the tach up to, well where is that wire back behind the gauges? I want to just splice into the same one that feeds my stock tach. I found a couple that are the same colors, but they aren't working. Can someone please tell me the exact wire and where it's located at behind the gauges? Thanks!
