Step-by-Step Guide
Step 1: Disconnect the Battery
The first step in any electrical work is to disconnect the battery to avoid short circuits. Locate the battery, and remove the negative cable to disconnect it.

Use the panel removal tool to remove the trim panel surrounding the radio. Once you’ve removed the panel, you’ll see the radio and the wiring harness. Disconnect the wiring harness from the back of the radio, and set the radio aside.
Step 3: Connect the Radio Wiring Harness
You should have a radio wiring harness that corresponds to your radio model. Use the diagram to match the wires on the harness to the wires on the car’s harness. Use wire strippers to strip the ends of the wires on both harnesses, then use butt connectors or a soldering kit to connect the wires together. Wrap the connections with electrical tape to protect them.
Step 4: Test the Connection
Before you put everything back together, test the radio to make sure it’s working correctly. Reconnect the negative battery cable and turn on the radio. If everything’s working as it should, turn off the radio, disconnect the battery again, and put everything back together.
