Ford chassis? It's there, either left or right of the steering column. Can be in a bundle of wires, have a cap on it or otherwise difficult to recognize. Mine was hard to find. Removed a piece of plastic trim under the column then could readily see it. Once known location don't need to remove the trim to get plugged into it.

Must be within 18 inches of the steering column. Sometimes they have a cover on them making the port harder to find.

I agree. Diesel does NOT have obdII.
Nice catch...didn't even pay attention to that.

Yellow warning light on. The light came on while driving with the generator on. All of the dash controls fluctuated wildly and then the light came on. I now believe that I have a bad relay between the coach and chassis battery. However I would like to turn the warning light off, because I don't believe that it was a true warning.

What makes you think diesels don't have a port for connecting a OBD reader?
MY Cat powered coach has 2 ...one in the cab near the steering column and one in the the rear curb side service bay.

Both of my DPs (08 Safari & 13 Phaeton) have OBD connectors just to the left of the steering column.

Diesels use a J1939 Diagnostic Plug for ECM communications, not OBD. It's a round 9 pin connector and there are usually two, one near the steering column and one near the engine.

Although may be true of "SOMEdiesel powered powered coaches", it's NOT true of "ALL diesel powered coaches".
My 3126 Cat powered coach has 2 " 6 pin J1708 Diagnostic Plugs".
When connecting my coach to their computer...my local Cat service shop uses an "adapter cord", (aka: a "wire harness").

So exactly what is the difference between an OBD connector and a J1939 Diagnostic Plug for ECM communications besides physical characteristics?

Back to the OP. Your connections should be either at the steering column(these can be really hidden) In the front electrical bay. or at the rear motor compartment. Once you find one and see how many pins are used a scanguageD will do what you want and will give you all your gauges and maybe a bunch of info you could use.
