Hey Carl, welcome back! You've done a great job of identifying the Lance 6-pin wiring functions and matching them up to the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box item # e99011. You don't need to worry about the blue wire for the trailer brakes so you can leave it open. You'll need to connect your Yellow Wire: 16 Gauge, Back-up Lights to the yellow wire on the junction box/7-way cable.

Did you just get your Lance camper? We get these questions frequently and it still amazes me Lance has stuck with their 6-pin connector.

Harness works well, just make sure you know how your vehicle is wired as the box may look color coded but its not plug and play

Thanks for the information. ?? As stated, it’s a 2015 Lance, so I don’t know if the new ones are standardized. I’ll order the item for a new hookup. ??
