negative side of the coil
On the distributor cap where the wiring hooks up is a terminal that says tach. Install the red wire to it and the black or ground wire to a suitable ground. Sometimes the tach has a green wire that connects to the white one coming from the ignition coil plug side that has 2 wires
Its EASY! just connect the (usually green) wire to the negative post on the coil. Hook up the power wires and the illumination wire and ground for the tach wire and ur done its easy!

You do need a switched live to the bat terminal, but not to the tach terminal. The tach terminal is the negative side of the coil, the bat terminal is the positive side of the coil. Normally the tach terminal is for the green wire from the tach.
