Installation Instructions
- Disconnect the negative battery terminal to prevent any electrical short or damage during the installation process.
- Remove the factory stereo from your vehicle by following the specific instructions for your make and model. You may need to consult your vehicle's owner manual or search for a tutorial online.
- Identify the factory stereo harnesses in your vehicle. There should be one or two connectors, depending on whether your vehicle has a factory amplifier or not.
- Match the color-coded wires on the Scosche GM02B harness to the corresponding wires on your aftermarket stereo's harness. Use the EIA industry standard color codes as a guide. You may need to consult your aftermarket stereo's manual for specific wire functions.
- Securely connect the matched wires using solder, crimp connectors, or electrical tape.
- Plug the Scosche GM02B harness into the factory stereo harness in your vehicle.
- Install the aftermarket stereo in your vehicle, following the specific instructions provided by the stereo manufacturer.
- Reconnect the negative battery terminal and test your new stereo for proper function.
Troubleshooting Tips
- If you have no sound coming from your aftermarket stereo, check if your vehicle has a factory amplifier. If so, connect the blue remote wire from the Scosche GM02B harness to the 12-volt red wire on the aftermarket stereo's harness.
- If you still have no sound, ensure that all wire connections are secure and properly matched according to the EIA industry standard color codes.
- If your vehicle has a factory amplifier and you are still having issues, you may need a different interface, such as the PAC ROEM-GM21A, which connects aftermarket radios to factory amplifiers.
