Hey John! To get your 4Runner lights working while flat towing you need the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Way Coiled Adapter Cord # RM-15267. This kit comes with everything required, including the 7-way to 6-way coiled adapter cord to run between your motorhome and the front of the vehicle. You probably want to add a charge line # RM-156-25 to this as well.
Do you have the rest of your parts picked out already? If you need additional recommendations for the rest of your setup let me know.
