The 2007 Dynasty, 2007 Executive, 2007 Navigator, or like PandK says, the 2007 Marquis should be nearly identical. The wiring diagram set that came with our Signature actually says Dynasty on the cover and has the extra pages for the Signature.
Northwest RV Supply has a 2007 Dynasty or 2007 Marquis wiring diagram set for sale.
