Parts Needed to Wire a Motorhome W/ Combined Lights to a Toad That Has Separate Lights

Question:

Have a 2020 Jeep Cherokee Trailhawk as a tow vehicle for 2022 Tiffin Allegra Open Road RV. Had tow wiring package commercially installed. When I brake - the tow vehicle brake is yellow. Researched and switched connection and now brake light still yellow and running light is red. Have been reading that I may be missing something like a RM 732 Converter Kit or something I do not know. Any help would greatly be appreciated.

I did some research and what I believe is happening is that your motorhome has combined lighting and your Jeep has separate and the brake lights are overriding the turn signal lights.

I contacted Roadmaster and they recommend to use the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 which include the diodes needed to fix the issue.

I have attached a wiring diagram and an install video for you to refer to.
