2000 GMC Truck V8 Two Wheel Drive Automatic 34000 miles
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?
