The Hopkins Endurance Multi-Tow 4-Way Flat to 7-Way RV Trailer Adapter w/ 4-Way Vehicle End Plug Item # HM47180 is the product that you need to connect to the 7-pin flat connector on you trailer. This part will allow the basic light functions of a 4 pin, while having a 7 way connection for your trailer.
This should be a simple install. This wiring harness plugs into your existing 4-way flat connector. Since you wont need the additional functions of the 7-way you don't need to connect the wires. Just use this part and plug in the 4-way in but the extra wires just need to be capped off. I have a step by step install video linked to this answer page, to simplify this process.
