Wiring question on my 2000 Monaco Windsor

Most Diesels that were wired or have the optional 12 volt Freezer/Refer, the wire is run to the RF storage compartments behind the RF tire. The first 2 compartments are where they installed the slide out tray and Freezer/refer. Doug-- Below the link is to the most common freezer/refer used back then. It states an Engel , but Norcold was the maker.
