It may not have one. You may have to find and install an extension cable. When OBDII was planned, it was never though to be a driver's tool.

My 99 Tradewinds on a Freightliner Chassis with a CAT 300 only has one in the engine compartment. 22 AWG twisted pair spliced in and run forward to a new connector works fine.

It took me quite some time to find mine on my 2000 Tradewinds 300 CAT engine it was under the transmission shifter. Round gray plug very high up there you have to stand on your ear to see it

If there is an OBD II Port on my motorhome I would like to get any and all information that I can out of it. So if someone can tell me where it is. I would very much appreciate it thank you.

Your Tradewinds does NOT have OBDII it has J1708 which needs a ScanGuage "D".
Displays limited data, four per screen but has many screens accessable by pushing a button.
ScanGauge - Trip Computer + Digitial Gauges + ScanTools

Or a SilverLeaf
Really the Cadillac of monitors and very costly.
