I am currently installing a used Roadmaster EvenBrake in our 2008 Mini S convertible.
Here is what I have found so far...
We had the front nose off to install the baseplate for towing last month, we should have mounted the breakaway switch then. Now we need to take some of the nose off again to mount the switch.
I haven't run the cable from the breakaway to the control box, but I don't expect it to be a lot of fun snaking it through the MINI.
I had to install a new lighter plug that was always LIVE to power the EvenBrake.
I also had to run power to the EvenBrake control box.
I need to install a brake light switch onto the brake pedal and wire that to the EvenBrake control box so that it knows when the brakes are being applied
The MINI brake pedal is too small for the EvenBrake adapter so I am going to need to fabricate an adapter to make it work properly
Once all this is done I expect the EvenBrake to work perfectly and be easy to setup and remove as needed.
Everyone says their system is easy to install but the MINI is mini and I am getting too old to fold myself up like a pretzel under the dashboard to do wiring and fabrication.
Good Luck with this project and I will be watching to see if anyone has found a better solution.
