Hi Jennings, welcome back! The Curt Universal Tail Light Wiring Kit # C63CR is not compatible with vehicles that have PWM electrical systems. Since you have this on your 2025 Ram 1500 the wiring kit won't work with your truck.
Regardless, a better choice would be the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267. The Roadmaster wiring is the most reliable, and it also comes with a 6-way so you can add a charge line kit # RM-156-25 to avoid a dead battery.
It looks like you already picked up the Blue Ox Base Plate Kit # BLU66ER. Do you have the rest of the parts picked out for your setup? You still need a tow bar, safety cables, and a supplemental brake system. If you're still deciding I recommend the following:
-Blue Ox Avail Non-Binding Tow Bar # BLU28QV (safety cables are included)
-Blue Ox Universal Tow Bar Cover # BLU53QV (optional)
-Curt RVi Series Shadow 2 Flat Tow Brake System # RVI94FR (permanent system, includes charge line)
OR
-Curt RVi Series 4 Portable Flat Tow Brake System # RVI44FR (add # RM-9332 if you need a 12v outlet)
If you use the Series 4 you will still need a charge line. You can use the Roadmaster I listed above or if you want something designed for the system/monitor the TBC+ # RVI74FR is also available.
The only other thing you may need is a high-low adapter like # e52ZV to keep your setup level. The base plate kit has a bracket height of 18/-1/2". Measure the distance from the ground to the center of your hitch on the motorhome and subtract to find the difference. Ideally this is 0 but the safe zone is anywhere between +/- 3" of the center.
Where are you headed once you get your Ram all set up for towing?

Thank you so much Robin. This is my 4th tow vehicle. I already have a Demco Stay N Play, a 6 wire metal female trailer wire connector, a Blue Ox towbar, and a leveling receiver. I really only need four diodes and the 20+ foot flat cable and a charge wire. Do you have a “smaller” kit available. Greg
