How do shift lights work?
When an engine reaches its shifting point, a shift light mounted in the driver’s line of sight will illuminate. Commonly wired into a tachometer or a rev limiter, a shift light will illuminate a bright light—typically mounted in the driver’s line of sight —when the engine has reached the shifting point.
How does digital tachometer work?
Each time a shaft rotates and the laser meets the reflector, light bounces back to a sensor in the tachometer. The tachometer counts each time this occurs. The meter will calculate the number of times the sensor is triggered over a given time and processes the result in revolutions per minute.
What does the shift light on a tachometer do?
Set the shift light on the tachometer if applicable. This light will remind you that it is recommended to change gears at the current RPM. Not all tachometers have the shift light feature. If your chosen tachometer does, follow the installation instructions to properly set the shift light. The shift light cannot be set if the engine is running.
What’s the best way to install a tachometer?
Locate the 12-volt switched dash lighting supply for the dashboard on the car fuse box. Attach the tachometer backlighting wire. Install a grommet in the firewall. It’s a good idea to install a rubber grommet where the wire (s) pass through the firewall as part of your installation.
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.
