Hello, I am looking for a 7 Pin round wiring harness to connect a 2018 855S Lance truck camper to a 2021 Chevrolet 3500. Thanks!

For your application I recommend installing the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 for an easy-access in-bed 7-Way socket on your 2021 Chey Silverado 3500, and then cutting off the 7-Way connector on your Lance and installing the Trailer Wiring 7-Way Upgrade Kit # HS381-9000 instead.

For whatever reason Lance has decided to install a non-standard 7-Way plug on their truck campers so there isn't anything that matches up with it. If you cut off the OEM 7-Way and replace it with the etrailer kit it will ensure that your truck wiring will work and it might make the camper easier to sell if you ever get to that point because you'll have the standard 7-Way wiring.

Please note that you'll be making your connections inside the junction box per function, and not per color.
