I hooked up the camper to the Jeep Grand Cherokee (1.5 yrs old) on Thursday evening and had running lights but no turn signals or brake lights.  Tried connecting the pickup truck and both the truck and camper lights worked great.  After borrowing my neighbors vehicle lift Friday morning, I've found that the engine's exhaust manifold had melted 9 wires in a wiring harness.  I called the dealer on Friday at noon and they had me bring it in right away, once they found out I'm leaving for Niagara Falls.  Everything is rewired at no charge and I'm still in business.  :banghead: I need this vacation.
