Yes, you can just plug in your 4-Way to the Hopkins Endurance connector, # HM47200, ground it, and not connect the remaining wires if they are not needed. You can tape them up and stow them out of the way. For future reference, the blue wire would connect to the brake output circuit from a trailer brake controller. The red wire would connect to the positive battery terminal via a 40 amp circuit breaker # PK54540. And the last wire would tap into the reverse light circuit.

Since your trailer has LED taillights we don't have a converter that will work. Normally we recommend the part #C56196 but this does not work with LED bulbs. Most likely have a converter already installed on the trailer wiring if it has been used…

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…

I do have a potential option for you, but we do not have any kind of custom fit wiring harness that will connect to the plug in your picture. Since there isn't an adapter to go from a semi 7-Way to an RV 7-Way the best solution is going to be to…

There isn't a plug-in style adapter for your application since the semi trucks have their brake lights separate from their turn signals. So what you'd want to do is install a 4-way first on the semi with the part #119190KIT and then convert…

The trailer connector used on most semi-tractors is a 7-pin round which is similar to a 7-way flat used on most RV's but the big difference between them is how the stop and turn signals are wired. The stop and turn signal circuits are separate on…
