How to Determine When Trailer Braking Power Adjustment Is Needed on Tekonsha Prodigy P2

The Tekonsha Prodigy P2 Trailer Brake Controller # 90885 is a great choice. This is a very nice proportional brake controller that will activate the trailer brakes at the same time and with the same intensity that you apply to them in your tow vehicle. It also has an easy-to-read LED display with continuous diagnostic check alerts.

After you install the Prodigy P2 and have it securely mounted in your tow vehicle, you will need to set the power to the trailer brakes. How much they need to be adjusted will simply depend on everything in your setup.

The best way to do this is to connect the dolly with the vehicle you are towing to your tow vehicle. With the engine running, hold manual full left on the controller and set the power knob to indicate approximately 6.0. Then drive your vehicle on a level surface at about 25 mph and fully apply the manual knob on the controller. If the trailer brakes lock up, turn the power down using the knob. If the braking was not sufficient, turn the power up. You will just repeat these steps until you have achieved sufficient braking power. You may want to then use the brake pedal in your vehicle to make a few low speed stops to see how everything is working.

I have also attached the installation details of this controller for you to review.

If you need to add a 7-way connector to your tow vehicle, you will use the Universal Installation Kit # ETBC7. I have attached some helpful articles about installing brake controllers from scratch.
