Proportional Trailer Brake Controllers have to be Mounted at a Certain Angle to Work Right
Updated 11/17/2011 | Published 11/16/2011
Question:
Why do the controllers have degrees marked and why how do you know which one to buy?

Expert Reply:
When you are looking at the proportional brake controllers (see link), you will see options for mounting at various degrees. What this means is the angle range at which a particular brake controller can be mounted. The reason this is important is because it cannot always be mounted flat (perfectly level) due to the shape of the interior on a vehicle.
You would choose one that had a wider range for more mounting options. The Tekonsha P2, # 90885, can be mounted 360 degrees in the direction of travel and not tilted side to side. If you look at the installation instructions I have linked for you, you will see a whole section on mounting the controller. I have also included a link to a video showing a typical installation.
If a controller was mounted incorrectly, outside of its range, it can have cause the braking to be too aggressive, too weak, or not function at all.
