Hey Martin. Here's a list of parts that are a mix of what you referenced and what I recommend using to flat tow your 2019 Ford Fiesta ST-Line:
Tow Bar and Safety Cables - Roadmaster Falcon 2 Tow Bar item # RM-520 and item # RM-643
Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - item # RM-524441-5
Protective Screen - Roadmaster Tow Defender Protective Screen for Towed Vehicles item # RM-4750
Wiring Harness - Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267
Battery Disconnect - Roadmaster Battery Ace Battery Disconnect w/ Key Fobs item # RM39ZT
Supplemental Braking System - Demco Stay-IN-Play Duo Flat Tow Brake System for RVs w/ Hydraulic Brakes item # SM99251
Brake Light Relay - Roadmaster Brake-Lite Relay Kit item # RM-88400
The only thing you missed is the battery disconnect item # RM39ZT. Other than that it was a well thought out and researched list.
The battery disconnect item # RM39ZT is a really convenient way of disconnecting your Fiesta's battery while it's being flat towed. You just have to hit a button instead of disconnecting the cables. Since your Fiesta has an automatic transmission disconnecting the battery is part of the flat tow procedure.
I couldn't find anything with the RM-250 part number on our site or Roadmasters but I assumed it was a tow bar based on the rest of the parts. The Roadmaster Falcon 2 Tow Bar item # RM-520 has a 6,000 lbs capacity and is compatible with the Direct-Connect Base Plate Kit - item # RM-524441-5 and the Tow Defender Protective Screen item # RM-4750.
The Demco Stay-IN-Play Duo item # SM99251 is going to be a better option than the Roadmaster InvisiBrake item # RM-8700 because it offers true proportional braking. It does not rely on a pressure based system that has to be retuned and adjusted like the InvisiBrake. Both are permanently installed and use a pressurize cylinder to press the brake pedal.
What kind of trips do you plan on taking if you go forward with flat towing the Fiesta you're looking at? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
