Installation Steps
Now that you have the wiring diagram and everything you need, it’s time to start installing your new radio. Here are the steps you’ll need to follow:
Step 1: Disconnect the Battery
Before you start working on the wiring, make sure to disconnect the negative terminal of your car battery. This will prevent any electrical shocks or shorts.
Step 2: Remove the Factory Radio
Use a panel removal tool to gently pry off the dash panel that surrounds the radio. Once the panel is removed, unscrew the factory radio and carefully disconnect the wiring harness and antenna.
Step 3: Connect the Wiring Harness Adapter
Take your new radio’s wiring harness and connect it to the wiring harness adapter. This will bridge the gap between your new radio and the factory wiring harness.
Step 4: Install the Dash Kit
Take the dash kit and snap it onto the new radio. This will fill the gap between the radio and the dash, creating a seamless look.
Step 5: Connect the Wiring Harness Adapter to the Factory Harness
With the dash kit and wiring harness adapter in place, connect the adapter to the factory wiring harness. Make sure to securely crimp or solder each connection.
Step 6: Install the New Radio
With everything connected, gently slide the new radio into place and secure it with screws. Make sure the radio is centered and level.
Step 7: Reconnect the Battery
Finally, reconnect the negative terminal of your car battery.
