That would be OBD I.. they can be anywhere, but usually on or next to the computer under the hood..

I purchased a handheld pcm programmer this past weekend at a Winnebago State Rally and the gentleman giving th erpesentation stated the OBDii port is within 26" from the driver's seat - by law. I don't whent his law was enacted so it might be different for your coach.

It took me about 5 minutes to find mine, hope you have an easier time!!!

OBD II yes.. OBD I no...

You may be looking for something that isn't there. The wide spread implementation of on board diagnostics did not happen until 1996 when the OBD-2 scheme was implemented. Some vehicles had OBD-1 or a manufacturer proprietary diagnostic capability prior to that date so you might want to actually confirm that your vehicle has one. I would suspect the early ports are more likely to be near the engine than the driver's seat inside.
