One of the most important components of a classic car is its instrument cluster. The instrument cluster in a 1968 Mustang is responsible for displaying key information about the car, such as speed, fuel level, and engine temperature. Without a properly functioning instrument cluster, it can be difficult to drive the car safely and accurately. In this article, we will provide a comprehensive guide to the wiring diagram for a 1968 Mustang instrument cluster.
Overview
Before we dive into the specifics of the wiring diagram, it’s important to have a general understanding of the instrument cluster and its functions. The Mustang instrument cluster consists of several components, including the speedometer, fuel gauge, oil pressure gauge, and temperature gauge. These gauges work together to provide the driver with real-time information about the car’s performance and status.
In order for these components to function properly, they need to be wired correctly. The wiring diagram is a blueprint for how the wires should be connected in order to ensure that the instrument cluster functions as it should. It’s important to note that the wiring diagram may vary slightly depending on the specific year and model of the Mustang.
Speedometer
The speedometer is one of the most important components of the instrument cluster, as it displays the car’s speed in real-time. The wiring for the speedometer can be found on the back of the gauge itself. There are four wires that need to be connected: a power wire, a ground wire, a signal wire, and a lighting wire.
The power wire should be connected to a 12V power source, while the ground wire should be connected to a ground point on the car’s frame. The signal wire, which is responsible for sending the speed signal to the gauge, should be connected to the speed sensor on the transmission. Finally, the lighting wire should be connected to the car’s lighting circuit, so that the speedometer is properly illuminated at night.
Fuel Gauge
The fuel gauge is responsible for displaying the amount of fuel in the car’s tank. The wiring for the fuel gauge can be found on the back of the gauge itself. There are two wires that need to be connected: a power wire and a sending unit wire.
The power wire should be connected to a 12V power source, while the sending unit wire should be connected to the fuel sending unit on the car’s fuel tank. It’s important to note that the sending unit wire may be color-coded differently depending on the specific year and model of the Mustang.
Oil Pressure Gauge
The oil pressure gauge is responsible for displaying the oil pressure in the car’s engine. The wiring for the oil pressure gauge can be found on the back of the gauge itself. There are two wires that need to be connected: a power wire and a sending unit wire.
The power wire should be connected to a 12V power source, while the sending unit wire should be connected to the oil pressure sending unit on the engine. It’s important to note that the sending unit wire may be color-coded differently depending on the specific year and model of the Mustang.
Temperature Gauge
The temperature gauge is responsible for displaying the temperature of the car’s engine. The wiring for the temperature gauge can be found on the back of the gauge itself. There are two wires that need to be connected: a power wire and a sending unit wire.
The power wire should be connected to a 12V power source, while the sending unit wire should be connected to the temperature sending unit on the engine. It’s important to note that the sending unit wire may be color-coded differently depending on the specific year and model of the Mustang.
