Trailer brake controller in used motorhome
« on: September 11, 2017, 04:26:19 PM »
I bought a Class C Motorhome that is on a 2016 Ford 350 chassis. This is a picture of part of a brake controller that was already in it. Does anyone have a clue what controller might fit that?

It looks like the diagnostic port.

Welcome to The RV Forum, John!

Bill's right, that's the OBD2 diagnostic port and has nothing to do with a brake controller.  You're looking for a grey 4 pin connector to attach an adapter cable for an external brake controller.

I'd take the motorhome down to a Ford dealer and let them look at it.  Ford has a superior built-in brake controller as part of their optional trailer towing package.  If you have it you'll have a small control panel on the dashboard. 

You can buy the panel on Ebay, but I don't know if it will work on a vehicle without the Towing Package.   That's where the dealer comes in, he can tell you if it will work or not.

On my 2010 ford E450 the brake plug for the bike controller was behind the center dash. Had to relay dig for it. Way up on top behind the three switches.
