Comparing the Tekonsha Prodigy and P2 Trailer Brake Controllers for a 2009 Chevy Silverado  

Question:

Expert Reply:

Yes, you can use either the original Prodigy or the new and improved P2, # 90885. The main differences between these 2 controllers is the mounting range and the functions. The P2 can be mounted a full 360 degrees in the direction of travel whereas the Prodigy can only be mounted positive or negative 70 degrees from level.

The other big difference are the functions. The original Prodigy is only compatible with electric trailer brakes. The P2 is compatible with electric trailer brakes and electric over hydraulic trailer braking systems.

The additional mounting options and ability to use the controller with electric over hydraulic brakes makes the P2 more versatile.

On a 2009 Chevy Silverado the tow package wiring is located under the dash, to the left of the steering column held together with a white tag. Once you are ready to wire in either brake controller you will attach the brake controller wires to the vehicle wires as follows:

Brake controller white to truck white for ground
Brake controller black to truck red/black for 12 volt power
Brake controller red to truck light blue/white for input brake stoplight circuit
Brake controller blue to truck dark blue for output to the trailer brakes
If there is an orange wire on the truck it will not be used

There may also be some additional connections you will need to make under the hood to make the tow package fully functional. I have included a link to an FAQ article that will help with this installation and the under hood connections.
