As far as I know from 2001 on our coaches have a round 9 pin diagnostic port located on the wall to the left of the driver's foot well. There is also one in the engine bay.
Does any one have a 12 pin rectangular connection as well? This picture is from a 2003 U320. Any idea what it does or why it is there?
Thanks
Any electronic coach 1996 or earlier should have a 12 pin rectangular OBD2 connector under the dash. I have an adapter to go to our ProLink 9000 from that. Not very expensive on ebay.
The U300s with the 2 cycle may be the only ones with the 12 pin as I don't know of any other early electronic Foretravels. I think the Allisons used the 12 pin also.

I am not looking for older coaches with the only the 12 pin connections, I am looking for 2001 and newer with both a round 12 pin port and a 12 pin rectangular port.
Why is it there and why was it added?
The picture posted is not a standard OBDII interface. They have angled sides and 16 pins.
I have both plugs. VMSPC is connected into the rectangle 12 pin plug.
I've got the same Richard. I'm also connected to the 12-pin now and have all data. The 9-pin worked, but did not show transmission gear info, retarder temp or odometer stuff in the trip meter.
We are the only 2?
Hum, will check today.
Scott, you will not find a 12 pin plug on a 2001.. It seems having both are only 2003s as far Is I have discovered yet.
Keith, we are two of a kind! Haha.
The ever changing world we live in?
So your '01 has both and my '03 has both. Need to ask
@fourdayoff if he has both on his '02, when he comes up for air.
I have both on my 2002
