Wiring Instructions
Follow these instructions to install an aftermarket radio in your 2003 Pontiac Grand Am:
Step 1: Disconnect the Battery
Before beginning any electrical work on your car, it’s essential to disconnect the battery to prevent any accidental electrocution or damage to your car’s electrical system. Locate your battery and remove the negative cable using a socket wrench. This will disable power to your car’s electrical system.
Step 2: Remove the Old Radio
Remove the old factory radio by unscrewing any mounting screws and gently pulling it out. You may need to use a special tool to remove it. However, some models may have a snap-in design that can be easily removed by hand.
Step 3: Disconnect the Factory Wiring Harness
Once you remove the old radio, locate the factory wiring harness and detach it from the radio. The wiring harness should have a clip or wire connector, which you can press down to release the plug from the radio. Be careful not to damage the wires or connectors.
Step 4: Install the Wiring Harness Adapter
Now, attach the wiring harness adapter to the wiring harness that was disconnected from the factory radio. It’s essential to ensure that you’ve connected the adapter to the correct wires. You can refer to the wiring diagram to confirm the correct connections.
Next, attach the other end of the wiring harness adapter to the new aftermarket radio. Be sure to match the wire colors to ensure that they are connected correctly. If your radio doesn’t have a built-in wiring harness adapter, you may need to splice the wires together using wire crimps.
Step 5: Install the Antenna Adapter
The antenna adapter connects the car antenna to the aftermarket radio. It’s essential to use an adapter that matches your car’s antenna connection. Connect the antenna adapter to the aftermarket radio and attach the other end to your car’s antenna.
Step 6: Test the Radio
Before reassembling everything, take a moment to test the radio to ensure that everything is working as intended. Reconnect the car battery and turn on the radio to see if it works.
