Just thought I would throw this out there. I recently purchased my 3rd Bronco - the first 2 are long gone though. All three have had a SunPro tachometer mounted to the steering column - none have worked until I rewired them correctly.
After looking at the SunPro website and calling the tech support line, thought I would post the very basic wiring info with the hopes of saving someone the trouble of doing the same thing. My understanding is that the newer versions have colored wires coming out of the back. Mine (including the previous two) is an older version with 4 pins deep inside of a hole on the back of the tach. If you take a flashlight and look, the pins actually have letters next to them (which are referenced in the drawing).
I should preface this with the fact that I have not rewired mine yet, but the drawing is based on what their technical guy told me over the phone. A couple of other things: I am not a graphical artist so no flack about the drawing and I have the large 3" SunPro Super Tach II with black face and chrome ring.
Hope this proves helpful to someone.
