The color wires that are important to the Tach operation are:

Light Blue and White in black sleeve are connected together and supply +12 volts.

Black wires are ground attached to the tach case.

Dark Blue with Black stripe, (has a red mark on it) wire is the points wire or the wire that provides the pulses for the tach for RPM.

All other leads are for the indicator lights which I removed for the picture. (I added the green dots which are marks for the lights)

You can test the tach at a convenient place at the firewall were the electrical parts are on the passenger side. +12 volts is there via the battery connection to the solenoid, Ground is the chassis, points is the wire that connects to the points.
I assume that the factory ignition system is complete IE capacitor in the distributor.

Nothing like a photo to accompany your description!

Way to go Jon! EXCELLENT!!
