I went to the Food Lion Auto Fair today at the Lowe's Motor Speedway in Charlotte. Boy they had a lot of Chevy stuff, but not much Ford that I could see. I did happen to find a few interesting things. One vendor had a sweet full-length early Mustang console with the hole for a floor shifter that would look SWEET in a Maverick ($125.00). I wanted it, but didn't splurge. I did buy a 3 inch Ford tach, application unknown, and I was hoping that someone here would be able to tell me what it's from, how to wire it up, etc. Please see the attached pics. I would guess that two of the wires go in circuit with the coil (one on either side) and two go in circuit with the headlight switch (it's got a light), but that leaves one wire unaccounted for. Any help is appreciated.
