Wiring the Radio

Step 1: Disconnect the Battery

Before you begin wiring, it is important to disconnect the battery to avoid any potential electrical damage to your vehicle or radio. Use a wrench to loosen the negative battery cable and remove it from the battery terminal.

Step 2: Connect the Power Wire

The power wire is typically a red wire that connects to the back of the radio. Connect this wire to the yellow wire in your Sonoma’s wiring harness, which provides constant power to the radio even when the vehicle is turned off.

Step 5: Connect Other Wires

Depending on your radio and your Sonoma’s wiring, you may also need to connect other wires such as an antenna wire, a remote turn-on wire, and a dimmer wire. Refer to the wiring diagram and your radio’s instructions to ensure you connect each wire correctly.

Step 6: Test the Radio

Once you have connected all the wires, it is important to test the radio to ensure it is working properly. Reconnect the negative battery cable and turn on the radio to test the sound and other functions.
