itdave,
Great Dane's got the right idea. I keep that drawing on my home PC and on my laptop, which is always carried in the motorhome. The laptop copy is what enabled me to "jury-rig" the
mid-chassis harness 12v battery lead problem and get home when my coach shut down on the road earlier this summer.
I have a wide screen monitor, and have used the Windows screen capture feature (Alt-Print Scrn) to print small sections of it onto a legal sheet of paper upon ocassion. Mostly, however, the diagram is most useful to trace what circuits go where over large areas, and the diagram is so huge that the only way you can do that is with a PC or laptop monitor.
Also, you should be aware that there are numerous changes in chassis wiring systems between model years 06 and 07. However, I believe that Six-Pack has the 06 diagram and will probably email you a copy if you ask him.
