Helpful Expert Reply:

First you are going to want to inspect the T-One Vehicle Wiring Harness # 118650 on your 2011 Mercedes Sprinter for any loose connectors or signs of damage. I do always recommend using Dielectric Grease # 11755 on the connectors as this will help protect them from developing corrosion inside the connector which could cause intermittent issues like you have.

Our 7-Way Kit # ETBC7 will connect to your 4-way and allow you to install the Tekonsha P3 # 90195 trailer brake controller.
