Wiring diagram fundamentals
The 2018 RAM radio wiring diagram consists of color-coded wires that indicate the function and position of each wire in the radio system. Understanding the color codes and their respective functions is fundamental to ensure the correct installation and troubleshooting of the radio system.
The wiring diagram is divided into different sections, including power supply, ground, illumination, speaker, and antenna. Each section represents a specific function and connects to different components of the radio system, such as the head unit, amplifier, and antenna.
It is essential to follow the wiring diagram’s instructions to avoid damage to the radio system and ensure that the system operates correctly.
Power supply section
The power supply section is responsible for providing sufficient power to the radio system. It consists of three wires, including a constant power wire, switched power wire, and ground wire.
The constant power wire provides power to the radio system even when the ignition is off, enabling the system to store presets and maintain the time. The switched power wire provides power to the radio system when the ignition is on, enabling the system to function. The ground wire provides a connection to the vehicle’s chassis, ensuring that the radio system operates correctly.
The power supply section’s color codes vary depending on the RAM truck model and year. Therefore, it is essential to refer to the specific wiring diagram for accurate installation.
Ground section
The ground section is responsible for ensuring that the radio system operates correctly. It consists of multiple wires that connect to different components of the radio system, such as the amplifier, antenna, and head unit.
The ground wires provide a connection to the vehicle’s chassis, enabling current to flow through the circuit. The ground section’s color codes also vary depending on the RAM truck model and year.
Speaker section
The speaker section is responsible for transmitting sound from the radio system’s head unit to the speakers. It consists of multiple wires that connect to different speakers in the vehicle.
Each wire’s position and color code indicate the speaker’s location and polarity, ensuring that the sound is transmitted correctly. It is essential to follow the wiring diagram’s instructions to ensure that the correct speaker wire connects to the correct speaker.
Antenna section
The antenna section is responsible for transmitting radio signals to the radio system. It consists of one or two wires, depending on the vehicle’s antenna type.
The antenna wire’s position and color code indicate the connection to the antenna, enabling the radio system to receive radio signals correctly.
