Which is the correct way to install a tachometer?

Tachometer installation can be as simple as connecting the tach’s sending wire to the negative side of the ignition coil, while other ignition systems feature a dedicated tach sending circuit. In either case, installing the tachometer incorrectly can cause significant damage to both the tach and ignition system.

Where do I find the pulse wire for a tachometer?

If you get a new tachometer, read the instructions to be sure. Locate the output wire from your distributor. Depending on your engine, there may be a constant-flow wire and a pulse wire to the tach, as well as the additional wires for the ignition, lights, and other components.

How many switches do you need for a tachometer?

Generally, there will be two switches–a 1 and a 2. Most of the time, both switches should be down for a 4 cylinder engine, while both should be up for an 8 cylinder. In a 6 cylinder engine, most of the time the 2 switch should be up and the 1 should be down. If you get a new tachometer, read the instructions to be sure.

Where does the green wire for the tachometer connect?

The green wire reads the electrical pulses from the ignition. For most standard ignitions it connects to the distributor primary or negative (-) side of the ignition coil. WARNING: Do not connect to coil on MSD ignitions. Some electronic ignitions have a tach terminal on the ignition box, the green wire may connect there.
