Hey Robert! Yes it can be a bit confusing with all the different styles, but I can help you out.
It sounds like you're needing the trailer side of the 7 way plug and harness, correct? If so, I'd look at the Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable - Trailer End - 10' Long # A10-7W10. This can be hard wired into your 7 way wiring, and it gives you 10 feet of cable to work with. You can just run it how ever long you need and cut off the rest.
The 7 way round plug is the standard style that simply plugs right into your vehicle's 7 way outlet at the back bumper. Let me know if this isn't what you were referring to and I'll dig deeper for you! I've attached an install video to help you out too.
Do you have any summer trips planned with the Forest River?

In February 2026 I upgraded the electrical components and wiring to my 2019 Rockwood A122S-ESP pop-up camper. One of the cables replaced was the 8-way cord. What I liked if this product was that it has the correct wiring gauges for the various function. For example, the hound and 12V wires come with 10awg some others were 12 & 14. Some other 7-way in the market come with your typical 12awg size, this may be fine depending on the application to be used. I have been running my new set up and I am very pleased with the results. I connected the 7-way cord to a wiring distribution box. I highly recommend adding this to the setup, it will make your life much easier later in when you have to troubleshoot electrical issues or replace the entire cord years later.
