Maintenance and Troubleshooting
Once my wiring was set up, I learned that regular maintenance is key to preventing issues. Here’s what I do:
- Inspect Regularly: I check the wiring and connections periodically for any signs of wear or corrosion.
- Keep It Clean: I clean the connectors to ensure a good electrical connection and avoid issues while towing.
- Test Before Towing: Before each trip, I test all lights and signals to ensure everything is functioning properly. It’s a simple step that saves me from potential headaches on the road.
