About a year ago I had my 2004 Jeep Liberty wired to tow behind our Winnebago Outlook. This weekend I installed the Jeep tow hitch and wiring harness (which is a plug in operation). When I tow with the Jeep Liberty, the brake lights, turn signals, and four-ways on the trailer function, but not the running lights when just the headlights are on. Is there something to the wiring of the lights that might have been done when wiring it to be towed behind our RV that is causing this problem? Near as I can tell, the trailer wiring is fine.
Any help would be greatly appreciated!!
