Not sure about the 07.5+ (havent had in issue with our 08 yet). I know there was a fuse for the trailer lights in my 2006 though that always caused problems with wagon lights. It should be in the engine compartment fuse box (driver side close to the hood hinge). If you look at the diagram on the reverse side of the fuse cover, you should see some fuses for a trailer connection.
