Welcome to the forum.
I caught the title to your thread before I really read what you are asking so the first thing I did was go scrounging around in my files to see if I had any wiring diagrams for that particular coach. I did find some PDFs of wiring but nothing that really could be associated with re-connecting a map light.
I may ask a moderator to move this to the
Newmar Owner's Forum as somebody there may know immediately how to help you with that connection.
In the meantime, I did find something you might want to download and keep in your files as it's the generic 12v electrical information for all 2006 and 2007 Newmar products. It very well might come in handy for future reference purposes if you have other wiring or fuse questions but I doubt if it will help you reconnect the wire to your map light. It will give a lot of good information about wire colors, fuse locations, etc., and some general wiring schematics however, and I believe the link has been posted previously over in the
Newmar Owners Forum:
12V ELECTRICAL 2006 & 2007 NEWMAR CORPORATION TECHNICAL SERVICE MANUAL
eta: ...and as
Argosy mentioned, it's always good to post some pics with your post when you ask questions or need help as it will sometimes clarify the problem for those of us who are not very good at interpreting questions people ask ...I'm really bad at that.
