69 tachometer wiring, which wire to connect?

[smokinrt]

Hey all you mopar mechanics!!  I installed my restored guage cluster last week. The Tic-Toc Tach isn't working, but the clock does.  I'm trying to remember which wires went where, even with the use of a wiring diagram, I have an extra brown 18 ga wire.  Now the diagram shows only a gray clock connector for the entire Tic Toc Tach connection.  So does anyone know if any connector slides onto the back of the Tach onto the male end thingy (kinda bent "L" shape) held down with one brass nut?

The long stud is 12V+ switched from the radio fuse...

The shorter stud with the spade terminal on it goes to the negative (-) side of the coil

The tach is grounded through the dash frame.
