Where would I locate the CBDII diagnostic plug on a newmar 2008 ventana?

I have changed oil and filter on our cummins 6.7 diesel pusher and the check engine light will not go off. How can I reset, and if a code reader is required, where is the plug located? Many thanks.

I believe it's under the steering column???

If there is a Check Engine light on, then there is a Diagnostic Trouble Code, then it has to be fixed. The code will give a diagnostician a good road map towards the fix that is needed. It is unlikely a clear the code fixes the problem. That's why it's illegal to do so (for a pro).
To get the correct scan tool to view / clear codes, you will need to know what protocol your vehicle uses. You can call Cummins with your VIN and they can assist.

Neal is correct, typically it is at the base of the steering column. It is likely a round connector about 1 1/2" in diameter. It may (should) have a cap on top of it. There also will be one in the engine bay, typically near the rear bumper for easy connection.

If you are looking for an "OBDII" connector, not sure yours has that. But that is a parallelogram connector that GAS vehicles use since 1996. Maybe you can't find it because it was built with a Diesel Deutsch connector (the round 9 pin one) instead.
