Grounding the Tekonsha Prodigy P3 on a 2017 Toyota Tundra

Question

Question:

I just recently bought a 2017 Tundra 4.6L It did not come with a tow package and after reading many threads on here I bought a Tekonsha P3. I took off the panel and everything seems to be working fine. I am wondering if where I grounded the wire will work. In the attached photo you can see that I ground the wire to a little stub connected to the gas pedal and circled in yellow. The ground wire did not reach to where I saw others ground it over by the brake circled in red. Is where I grounded it going to cause any kind of problems? Thanks for the advice!

Although the stud you have the ground wire on your Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 connected to in your 2017 Toyota Tundra may still allow for the brake control to function properly, it appears that if there is paint underneath and it is not a direct part of the body/frame which is only going to cause problems down the road. I recommend extending the wire to the metal to metal ground you have circled in red with part # 12-1-1 and part # 05732-2.

If you are only getting the 8 volts when you pull the pin using a meter like #PT89ZR, that has nothing to do with your brake controller as the breakaway battery is powering that from the trailer itself. You can confirm your brake controller is…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

Sure, I can help with that. I can see why the fitment notes are confusing. For a 2012 Toyota Tundra with the factory tow package and factory 7 way connector, you'll want a brake controller that plugs into the factory brake controller port under…
