- Quick Splice Connector (provided)
- Additional Wire (if needed for reverse light connection)
- Cable Ties (optional)
- Silicone Sealant (optional)
Overview:
This adapter converts your 4-way flat trailer connector to a 5-way flat, adding reverse light functionality for trailers with reverse lights or surge brake lockout systems.
Step-by-Step Instructions:
1. Mount the Adapter:
- Select a suitable mounting location near the hitch and securely install the adapter.
2. Connect the 4-Way Plug:
- Plug the 4-way flat connector from the adapter into the existing 4-way flat connector on your vehicle.
