What is the Difference Between the Tekonsha Prodigy P2 and the P3 Brake Controllers

Question:

Im looking at either the P3 or the Prodigy P2. The major differences I see are 3 axis accelerometer in the P2 vs 1 axis in the P3. Looks like that would essentially eliminate alignment issues. The other difference seems to be the display capability and fault detection. Am I missing something here?

Actually, the P3 now has the upgraded axis accelerometer like the P2. The Tekonsha P3 Trailer Brake Controller # 90195, will work with both electric over hydraulic brakes on the trailer as well as electric brakes. It has a menu option on the display that allows the user to switch between the two systems. I have included a link to the installation details for the P3.

The P2, # 90885, will also work with both electric brakes and electric over hydraulic brake systems but the mode is selected differently since it doesn't have the same kind of display as the P3. The P2 is more of an entry level brake controller; easy to use, easy to mount, and it works well. That is probably why it is one of our most popular and highest rated brake controllers. I have also included a link to the installation details for the P2 below.

what harness is required if I was using the p3 on a 2008 gmc sierra?

If your 2008 GMC Sierra has the factory 7-Way then there is a wiring harness up under your dash that you will splice the pigtail from the P3 # 90195 to. If you don't have the factory 7-Way then you're going yo need to also install either part # PK11898 or part # 30955 .

I have a 2018 Mercedes GLS--would the Tekonsha P2 or P3 be better and which harness is required? Thanks much.

I would definitely go with the Tekonsha Prodigy P3 # 90195 . It's just a nicer controller with a larger display for easy-to-read settings, etc. For your Mercedes GLS you just need the Plug-In Harness # 3066-P .

Which Tekonsha wil be better for a 2020 Toyota Tacoma trd 4x4 ? P2 or P3?

I definitely recommend going with the Tekonsha Prodigy P3 # 90195 . I think it has a better display (easier to read messages, settings, etc) and I really like the option to store different settings. For your Tacoma you just need to add the Plug-In Harness # 3031-P to allow for a simple plug-and-play installation.

Will the p3 install on a 2014 ram big Horn? Or should I go with the p2. It looked to me there might be an issue with the wiring harness for the p3 and the 2014 ram

The same wiring harness is used for both the Tekonsha P2 and P3 Brake Controllers, and either option will fit and work well on your 2014 Ram. I like the P3 a little better because of its great display. Regardless of which model you go with, the Tekonsha # 3023-P will allow for an easy plug-and-play install.
