2007 Troopy 4.2 TD RV, OBD-11 Port?

Just wondering if anyone can tell me if, and where the Troopy has an OBD-11 port?
I have done a search and google etc posted on the troopy forum but still do not know.
I have looked around under the dash but nothing seems obvious.
It is ECM computer controlled and has the drive by wire throttle, so I assume there must be a port somewhere?

I am not on good terms with the dealer where I bought it (long story!)

And yes I want to fit a Scangauge-11
