You didn't give your exact model number, but you said "26 foot" so here is the link to the 2006 Outlook model WF326A which is the only "26" in the Outlook listings for 2006.
This is the link to the complete wiring diagrams for the coach and chassis interface, you would do well to download it and save it on a thumb drive. You can also look at or download various sections of it.
