200? Lance truck camper with the little round plug. We just got it back from the dealer after having a hitch and tie downs installed and they put a new round bed liner plug in for this new lance plug. Our previous camper used a big round "blade" connector and there is a connector in the bed that worked with that camper just fine.Well I forgot to test the lights when we were at the lot, while everything inside works fine, the turn and tail signals are all wonky.If I turn on the left turn signal, nothing happens.If I try the right turn signal, all the tail lights blink like the hazards are on.The brake lights seem sporadic.I presume something is crossed up or some wires are making contact that shouldn't.The dealer will let me bring it back to fix it but they don't have shop time for over a week so if I can just reconnect some wires that are connected wrong then that will save me time.Ideas?

Sounds like the wiring wasn't installed correctly to me. For the sporadic brake light, I would start by checking the connector and ground. This link is the one I used to wire my Lance 185s. Hope this help.Lance Plug

The truck plug shouldn't power anything inside the camper when the truck is off so trailer wiring shouldn't affect it. If the old plug worked fine before for sure then they messed up the wiring to the new plug. They just put a different style plug in the bed right, same wiring? Or if it's a new to you camper, is the camper wiring messed up?If you want to fix it yourself you need to know which prong powers what and be handy with a multimeter or at least a test light?

In the meantime you could try these.... http://www.harborfreight.com/12-volt-magnetic-towing-light-kit-69626-8847.htmlAlthough you may have to find a different means of fastening as the rear bumper is most likely aluminum.

My Lance has another small plug, its either for a rear camara or ? ,I forget. You sure your on the right plug?
