Recommendation for Wiring a Camper to a 7-Way Wiring Connector

Question

Question:

I have a 2006 Dodge Ram 3500 with a 7 pin plug at the bumper and 1 - 7 pin plug 8foot away at the front of the bed. I was contemplating tying the modulite in at the current splice point in the truck factory harness. The modulite will only need to control the turn signal and stop lights on the trailer and camper at the moment. Sensor wires would either have to be run aft to the rear tow vehicle lights or forward to the front signals. Does this seem feasible? Also, with only one stop wire in the modulite, how does it send stop signal to both left and right tail lights?

What I would do in your situation is take a trailer side 7-way like the # H20046 and make an adapter out of it for your camper. So when the camper is in your truck you could just plug in the adapter to the 7-way located in the truck bed.

Without knowing what the wiring of your camper is like I attached a picture of a chart that shows the wiring code of the # H20046 so you would know how to wire it to your camper.

This will allow your trailer to still be able to use the 7-way at the rear.

I can't be certain what the function for each of the wires are on your new trailer lights, but one of the three wires is likely for ground. Your old/existing trailer lights grounded through their mounting hardware, which is why they only had two…
