Fig. Fig. 1: Connect one tach lead to the tachometer terminal on the HEI system

Connect one tach lead to the "TACH" terminal on the side of the distributor and the other to ground. Some tachometers must be connected to the "TACH" terminal and the battery positive terminal. Not all tachometers will operate correctly with the HEI system. Check with the manufacturer if there is any doubt.

The "TACH" terminal should never be connected to ground.

When hooking up a remote starter switch, disconnect the "BATT" terminal.
