Tic Toc Tach wiring

[OldToys]

Tic-toc-tach wiring, on my 69 Super Bee
I am trying to get my clock working but doesn't appear to have a constant 12 volts to the gauge. I have two wires plugged into the back one spade and one post connector. It requires both to operate the tach. Can someone post a pic of the rear of the gauge? I'm not sure how the clock gets its 12 volts.
Thanks,
Tim

Sorry false alarm, I found a wire with a spade connector and constant 12 volts tried it with what appeared to be a light socket with a short lead. It is the 12 volts to the clock, and it works, good day of trouble shooting.
