<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: 72-SS-L48</div><div class="ubbcode-body">The car has its original ignition system. The tach is wired with three wires.

One wire as the ground, one going to the coil and one plugging into the fuse box.

Mind you the tach worked when I pulled the car out of the garage, I went to swap tachs and nothing!

a forth wire would be for lighting the tach face, spliced into dash light circuit.
