We have a 2006 Allegro Bus Cummins 400HP. Does anyone know where the J1939 plug is located on the engine for a VMSpc Silverleaf engine monitor Jib. And what kind is it. How many pins and size.
On my Foretravel, it is located on left side wall in front of knee under dash. No longer able to drive with out it, only thing on dash now is the air pressure gauges, everything else is on the VMSpc, much more info than I ever imagined. Dave M
