Question:
Good morning, I am looking to add a 7 pin plug and a trailer brake controller on our church’s 2015 E-350. Can you advise on products and install? I have photos of several harnesses with dummy plugs near the 4 pin that is already installed. It looks to have a fuse in the trailer brake spot in the fuse block under the hood. But unlike my F-150, there is no place to plug in a TBC. I don’t mind wiring and running wires, I just need to know the best route. Thank you! Ethan

Hey Ethan, if your 2015 E-350 has a 7-way wiring harness the correct part number you'd need is the part # A10-7072VP which would plug right into a round connector that looks just like the part # 20147.
With that said do you have a 4-way currently and are looking to install a brake controller? If that's case you would need the part # ETBC7 with a brake controller like the part # 90885.
