An RPM gauge, also known as a tachometer, measures engine speed in revolutions per minute. Begin by selecting a location to place the tachometer, and install it using components that come with the kit. Drill a hole in the firewall where the tachometer wiring goes through to the engine compartment. Connect the wires from the tachometer to the appropriate wires on the vehicle.
Purchase a tachometer from an auto parts supply store or salvage yard. Gather necessary tools such as a sharp knife, wire cutters or strippers, ratchet or socket, screwdriver, drill, tie wraps and rubber grommets.
If a hole does not exist in the firewall, drill one where the wiring can go through into the engine compartment. Install a rubber grommet to prevent wire fraying. Mount the tachometer in a desired location using the parts that come with the tachometer.
Run the wires through the hole in the firewall and mount them to the firewall of the engine compartment as needed. Connect the black wire to the engine’s grounding connection. Connect the green wire to the electronic coil negative post. Connect the white wire to the dash lighting. Connect the red wire to the ignition switch.
Start the vehicle and ensure that the tachometer is working; use electronic testing tools or take the vehicle for a test drive.
A car that is cold has a fast idle to quickly bring it to optimal operating conditions. This is a part of the design of the engine. Older vehicles with carbureted engines have a choke to increase the idle speed to as high as 1200 rpm, or revolutions per minute, until the engine warms, according to About.com.Full Answer >

An oil pressure gauge can fluctuate for many reasons, including an actual automotive problem as well as reasons like fluctuation in oil temperatures. In most cases, the gauge will fluctuate to indicate low oil pressure. When the gauge fluctuates to indicate high oil pressure, it is often indicative of a pressure relief valve problem.Full Answer >
