PCBFM103 Wiring Diagram Installation Guide

Installing the PCBFM103 PCB in your car can be a challenging task, especially if you are not familiar with electronics or car electrical systems. Here is a step-by-step guide to installing the PCBFM103 wiring diagram:

Step 1: Gather the Required Tools and Materials

Before you begin the installation process, you will need to gather the following tools and materials:

  • PCBFM103 PCB
  • Soldering iron and solder
  • Wire cutters and strippers
  • Electrical tape
  • Heat shrink tubing
  • Antenna cable
  • Speaker cable
  • Power cable
  • Ground wire

Step 2: Remove the Radio Module

The first step is to remove the existing radio module from your car. This can usually be done by removing the panel around the radio, and then unscrewing or unclipping the module itself. Make sure to disconnect any cables or connectors that are attached to the module.

Step 3: Connect the Antenna Cable

Next, connect the antenna cable to the PCBFM103 PCB. The antenna cable should be connected to the ANT terminal on the PCB. Use a soldering iron to secure the connection, and cover it with heat shrink tubing to protect it from damage.

Step 4: Connect the Speaker Cable

Connect the speaker cable to the PCBFM103 PCB. The speaker cable should be connected to the SP+ and SP- terminals on the PCB. Make sure to connect the positive and negative wires correctly, as this can affect the sound quality. Secure the connection with a soldering iron, and cover it with electrical tape or heat shrink tubing.

Step 5: Connect the Power Supply

Connect the power supply to the PCBFM103 PCB. The power supply cable should be connected to the VCC and GND terminals on the PCB. Again, make sure to connect the wires correctly, as this can affect the performance of the PCB. Secure the connection with a soldering iron, and cover it with electrical tape or heat shrink tubing.

Step 6: Connect the Ground Wire

Connect the ground wire to the car’s chassis. This will provide a stable ground connection for the PCB. Use a wire stripper to remove some of the insulation from the ground wire, and then secure it to a grounding point on the car’s chassis. Make sure the connection is secure and safe.

Step 7: Test the PCB

Before you replace the radio module and panel, make sure to test the PCBFM103 PCB. Turn on the car’s ignition and switch on the radio. You should be able to pick up FM radio signals and hear them through the speakers. If there are any issues, check the wiring connections and make sure they are correct and secure.
