I am sortign through a rats nest of wires as I chase down shorts on my 74 bronco. When I pulled the instrument cluster I discovered a litttle black box that is 2.5 x 2.5 X 1 it is made of balck plasic and has a 7 inch shielded wire coing out of it that was cut and not connected to anythign. It was held in by one phillips head screw connecting it to the frame. On the box the only letters and numbers that appear say "the unc-o box" Does anyone know what this box was supposed to do and if it still has a purpose?
