    Could be an external shift light driver? Color mode switch line?

    Also, it may be better to wire the white to the parking/marker lights.

    Wire colors for tachs are not standard so you need to find out who makes it. Once you have done that a quick google will probly find you the wiring schematic. If it was and older tach that needed a module then this site would probly be able to help as some of the old stuff is just non existant on the web. Not being a dick but mods will probly kill this thread as OFF TOPIC.

    Orange wire goes to Battery (12 volt Positive side). I have installation instructions somewhere.
