CB radios are a popular means of communication. They are used by truckers, off-roaders, and hobbyists. One of the most important components of a CB radio is the microphone. The microphone is used to transmit the user’s voice over the radio. Most CB microphones have four pins, and each pin is connected to a specific wire. In this article, we will discuss the color 4 pin CB mic wiring diagram.
Understanding the Wiring Diagram
The wiring diagram for a 4 pin CB microphone has four wires. Each wire is colored differently and is connected to a specific pin on the microphone plug. The colors of the wires may vary depending on the manufacturer of the microphone. However, the standard colors for the four-pin microphone wiring are red, black, white, and blue.
The red wire is the positive wire and is usually connected to pin number one on the microphone plug. The black wire is the negative wire and is usually connected to pin number two. The white wire is usually connected to pin number three and is used for transmitting audio signals. The blue wire is usually connected to pin number four and is used for receiving audio signals.
Wiring the Microphone
The wiring of the microphone must be done correctly to ensure that the CB radio operates properly. Follow the steps below to wire a 4 pin CB microphone:
- Strip the insulation from the four wires of the microphone.
- Identify the positive wire which is usually red.
- Solder the positive wire to the pin number one on the microphone plug.
- Identify the negative wire which is usually black.
- Solder the negative wire to the pin number two on the microphone plug.
- Identify the audio transmission wire which is usually white.
- Solder the audio transmission wire to the pin number three of the microphone plug.
