Can I Use My 7-Way Truck Wiring To Wire My Lance Camper Harness To My 2018 Ram 3500  


Truck: 2018 Ram 3500 Dually with in-bed 5th wheel plug AND bumper hitch plug. Camper: 2019 Lance 850 Question: Where and how to wire in the Lance harness that comes with the trailer? Lance harnesses use 8 ga. wire, with main +/- going directly to battery, and I dont want to go down in wire size for safety and efficiency reasons. Can I install the Lance harness into my current system without having to use any adapters, etc.?


Expert Reply:

I found the owner's manual for your 2019 Lance 850 and it does recommend to use 8 gauge wire with their proprietary connector. Using the 8 gauge wire from truck battery to the camper ensures you have adequate amperage to the accessories in your camper.

Since the vehicle's current wiring for the 7-way is not 8 gauge wire I do not recommend splicing into that wiring to install the camper's plug onto the vehicle. I recommend wiring the Lance vehicle plug into the truck separately or take it to the Lance dealership to have it installed.

We do not have an adapter that would adapt the 7-way plug on your bumper to accept the Lance's molded camper connector on the 2019 Lance. The hole pattern on the Lance's molded camper plug is different than the standard plugs we carry.
