Open Road Diagnostic Connrctor

Ok I am lost. I have a check engine light comming on then going off, after a very short time. I am going to take it in to have it looked at. My mechanic asked to find the data plugs, he is a great diesel mech. but usally does not work on motorhomes. I know there is a 9 pin and most likly a 4 pin. But I can't find either.

The coach is a Tiffin Alleago Open Road 35TSA

Does anyone know where these are?
  • You'll probably have better luck posting this on the Tiffin forum where someone with a similar rig may read it. FWIW, different coach but I too have one under the dash (adjacent to the steering wheel column) and a second one on the engine (passenger side at the height of the head). Good luck.
