I am moving our Silverleaf unit serial #B12U1029, software 20RV02 3/17/00 from our older Safari motorhome to our newer 1999 Itasca with a 5.9 Cummins with a 6 speed Allison. The Safari had a CAT engine. There are wires marked for "power", "headlights" and "ground". There also is a white wire and a black wire that I assume goes somewhere into the engive electronics. Would really appreciate some help in determining where these two wires go. Thanks LeRoy
