I have 2017 North Trail 22rBK & am towing it with a 2014 Ram 1500. Hooked up to go for a trip Friday & the error message "check trailer brake wiring" came up. Thought maybe it was a fuse in the truck, but those look OK. Also cleaned up the plug & receptacle & still not connecting. trying to find out if this is an easy fix or if I need to get it in for service. Any help appreciated. Thanks.
