lizzy, part has been ordered, i se in the tach instructions to hook the white wire to cab light source, and black to battery, green to the adapter but where does this adapter read the rpms from? did it include instructions?
lizzy, i was reviewing the wiring diagram thru haynes manual, where did u tap into your ignition and light switch at for yours, and i still have yet to receive the tach adapter. i see the green wire runs to the adapter but where do i have to tap into in order to get the signal for the tach to read revs?
