Using the wiring diagram as a guide, connect the wires from the new radio to the corresponding wires in your vehicle. You may need to strip the ends of the wires with wire cutters or pliers before making the connections.
Be sure to secure all of the connections with electrical tape or wire connectors to prevent any accidental disconnections or shorts.
Step 4: Mount the New Radio
Once all of the wires are connected, mount the new radio into the dashboard using the appropriate mounting kit. This may require drilling new holes or adjusting the size of the opening in your dashboard.
Step 5: Reconnect the Battery
Finally, reconnect the battery and test the new radio to make sure it’s working properly. You may need to adjust the settings or wiring if there are any issues.
