To hook up the wires from the Boss Audio 637UA head unit harness to the existing wires from your Pioneer system, simply match the wire colors together. For example, the red wire from the Boss Audio 637UA head unit harness should be connected to the red wire from the Pioneer system harness.

Once you have connected all of the wires, you can turn on the Boss Audio 637UA head unit and test the audio system to make sure that it is working properly.

Important: It is important to note that some Pioneer head units may have different wire colors than the ones listed above. If you are unsure of the wire colors for your Pioneer head unit, please consult the owner's manual.

1. Refer to the wiring diagrams or user manuals of both the Pioneer system and the Boss Audio 637UA. This will help you identify the correct wire functions and their corresponding colors.

2. Match the functions of the wires in both systems. For example, if the yellow wire on the Pioneer harness is for constant 12V battery power, ensure that you connect it to the corresponding wire in your Boss Audio system that serves the same function.

3. Carefully strip the ends of the wires in your Pioneer harness and Boss Audio system. Twist the corresponding wires together, ensuring a secure and solid connection. You can also use solder or electrical tape to reinforce and insulate the connections.

4. Once all the wires are properly connected, use nylon wire ties or electrical tape to organize and secure the wires, preventing them from coming loose or causing any issues. It's worth noting that while it is technically possible to connect the two systems using this method, there are potential risks involved. Incompatibility between the systems or incorrect wiring can cause malfunctions or damage to the equipment.

If you're unsure about the process or want to ensure a professional installation, it's best to seek the assistance of a car audio technician. They will have the expertise to make the connections accurately and safely.
