Step by Step Guide
Before installing the aftermarket radio, you will need to disconnect the car battery. This will help prevent any electrical issues that may damage the car’s electrical system or cause injury to the installer. Once you’ve disconnected the battery, follow these steps:
Step 1: Remove the Factory Radio
The first step is to remove the factory radio from your car’s dashboard. You will need a panel tool, which you can purchase from any auto parts store. The panel tool will help you remove the trim panel without damaging it. Once you’ve removed the trim panel, remove the four screws holding the radio in place. Pull out the radio and disconnect the wiring connections at the back of the radio.
Step 2: Connect the Wiring Harness
Connect the wiring harness to the aftermarket radio. The wiring harness will come with a connector that matches the factory radio’s connector. Connect the harness to the radio and make sure it’s secure. Once you’ve connected the harness, connect the antenna cable to the radio.
Step 3: Connect the Wiring Harness to the Car’s Wiring System
The next step is to connect the wiring harness to the car’s wiring system. The wiring harness will come with a color-coded guide that matches the car’s wiring system. Match the wires according to their colors and connect them to the corresponding wires on the car’s wiring system. Once you’ve connected all the wires, tuck the wiring harness behind the radio and secure it in place using the screws that held the factory radio.
Step 4: Test the Radio
Turn on the car to test the radio. Make sure all the speakers are working correctly and the radio is functioning. If everything is working correctly, replace the trim panel and secure it in place using the panel tool.
