Question:
Why are the diagrams the same on you instructions for 2 to 3 wire and 3 to 3 wire illustrations? I need a 3 wire from motor home to 2 wire flat tow.

I attached a diagram for the 3 wire install of the Roadmaster kit part # 154-792-118158 which can be used as a guide for installing the part # TR118821 as well.

Thanks for the info! For flat tow wiring I recommend using the Roadmaster Diode Kit # RM-15267, which will give you a 6-Way connector at the front bumper and enough coiled wiring to go from there to the 7-Way on the RV. Then for trailer wiring you can use the Tekonsha # 118786, which will plug right in-line with the rear tail lights to provide you with a 4-Way for connecting to the trailer. Finally, for a trailer hitch the etrailer # e98856 will work perfectly.
