This is a 30 ft Georgetown Class A Motorhome on a Chevrolet P chassis with a 454 engine. I have a "Service Engine Soon" warning light. I have a loaner scanner but cannot locate the 16 pin port to connect the scanner. It is supposed to be on the left side under the dashboard. I have a call into Georgetown but no response yet. Can you point me to the scanner port?

This may or may not help, I do not have access to the "P" manuals, but G3500 RV Cutaway it's on left side under the dash as shown here...

I found the port - it had been covered by a decorative vinyl boot that covered the opening in the dashboard for the steering column. Thanks.,
