Using this Crawford front bumper light wire harness is easy. First, make sure your vehicle is the right model (2018 - 2023 Crosstrek or 2019 - 2023 Forester). The harness is custom - made to fit the Crawford front bumper, so just align it properly and start the installation. The race - style wire plugs will help you connect the power and pods securely. When it comes to maintenance, check the mesh sheath regularly for any signs of damage. If you notice any cuts or frays, replace the mesh to keep the wires protected. The relays and fuses are integrated into the harness and can be easily accessed on the Crawford Performance Circuit Board. If a fuse blows, replace it with the same type. Keep the circuit board clean to ensure a good connection. Also, when you're not using the lights for a long time, it's a good idea to disconnect the power to prevent any potential battery drain.
