1. Get a tachometer and splicing connectors. You can either buy a tachometer new, which usually run somewhere between $30 and $50, or salvage on old one for relatively cheap and install it into your car. The only other specialty item you'll need to complete the job is a package of quick-splice connectors, which are usually only a few dollars at the auto part store. The wires are about 16-18 gauge usually, so get connectors of the appropriate size.
2. Adjust the tachometer for the number of cylinders in your engine. New tachometers may be set to work on 4-, 6- or 8- cylinder engines by removing the back cap of the tachometer to reveal the cylinder setting switches inside. Set the cylinder switches to match the number of cylinders in your engine. Replace the end cap of the tachometer carefully to avoid pinching any of the internal tachometer wires. Use a screwdriver to refasten the end cap if necessary. 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.
3. 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. It's important to make sure you've got the correct wire for the tachometer, which means you might need to use a multimeter with a tach setting to test the wires correctly, and consult the shop manual for your engine. It's also important to note that some new tachometers are incompatible with solid-core spark plug wires and can be dangerous to connect without following the proper installation instructions for the tach.
4. Test the connection. Before you mount it in the steering column, it's a good idea to hook up the wiring and test it out while you rev the engine, to make sure it works. You don't want to go drilling holes in your steering column before you're sure you've got the wiring figured out. After you hook it up to the proper wires from the distributor and ground it correctly, it should give you an accurate reading of your RPMs as you rev the engine. Ground the tachometer. Attach the tachometer ground wire to an engine ground of the car. This need not be directly on the battery. Much of the car frame is grounded to the battery by sturdy wires. Trace those wires to find a suitable attachment point. Attach the tachometer pickup wire. The tachometer wire must be fed through a grommet in the passenger compartment to reach the engine compartment. This attachment point will vary from engine to engine.
