Recommended 7-Way to 4-Way Adapter for a 2023 Sprinter 2500
Updated 09/12/2025 | Published 05/24/2025
Question:
Hello, I have a 2023 Sprinter 2500 with factory installed trailer wiring leading to a 7 plug connector. I have a 4 pin flat connector on my boat trailer. What is the best way to make these work together? Is there an adapter from 7 to 4? Thanks for any help..

Yes, there is an adapter Steve. You'll want the Hopkins Endurance Multi-Tow Trailer Connector Adapter item # HM47570. This adapter will simply plug into your Sprinter's 7-way connector and provide you with a 4-flat to control your boat trailer's lighting functions.
This adapter also includes a 5-way connector incase you're ever pulling a boat trailer with brakes.
If you have any additional questions, go ahead and throw them into the comment box below.
