One thing about the wiring diagram in the document center, it shows the MOST stuff your
Trillium can have. A lot of the
electrical stuff were options. So my 1300 for example didn't have a
battery. But the wiring was there to add one.
I found the wiring diagram in the document center to be VERY accurate as to physical wires in my rig and the color coding, but appliances and stuff were options. Just one example,
fridge was an option, yet the diagram shows one (mine did come with a fridge). On and on it goes.
To make your trailer most useful, installing a modern power center AND a
battery are must dos IMHO.
