Is Wiring Converter Needed for Flat Towing 2015 Mini Cooper


Do I need a converter to use this wiring harness? My wayfarer is a combo lights and mini is separated. Do you have a picture showing where the vacuum tube that you splice into in 2015 Mini Cooper turbo? SM99231 Thx

That's a good question but a wiring converter is not needed to install the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 on your 2015 Mini Cooper. Since it has separate lighting and your motorhome has combined lighting you can add Tail Light Converter # 118158 if you want to retain your Mini's separate turn and brake signals but it isn't a requirement.

In regards to the airline you will run the vacuum line of the SMI Stay-IN-Play DUO Supplemental Braking System # SM99251 from, I have added a photo pointing it out. You can see this in the linked video install of this kit on a Mini as well, starting at roughly the 13:00 mark.

There are some other parts you'll need to flat tow your '14 Mini as well:
- Base Plate Kit: Roadmaster Direct-Connect Base Plate Kit # RM-521882-5 (S Model - Hardtop or Convertible) or # RM-521884-5 (Base model - Hardtop)
- Tow Bar: Roadmaster Falcon All Terrain, Non-Binding Tow Bar # RM-522
- Safety Chains: RoadMaster 68" Single Hook, Coiled Safety Cables # RM-643

You may also need a high-low adapter in order to keep your Mini Cooper level, and I've added a link to a help article which shows you how to determine if you need an adapter as well as a link to our selection of adapters. Additionally, I have added links to instruction manuals, video reviews and installations for you to take a look at.
