  If there is a round 7-way trailer connector at the rear of your 2012 Toyota Tundra all you would need to install the Prodigy P3 Brake Controller part # 90195 would be the correct harness part # 3040-P.

  Since your 2014 Toyota Tundra has a towing capacity that is 1,000 lbs over the 8,800 lb dry weight of your trailer you will need to be pretty cautious. If you don't plan on loading anything up in the trailer then the 1,000 lb of cushion is great but if you will be loading the trailer up to the max towing capacity of your Tundra you will need to be very careful.

• My Recently Installed 7-Way is Not Working on my 2011 Toyota Tundra What Can it be
  The Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package part # HM11143395 has two leads that should be connected. If those are both connected then your truck was not equipped with the factory wiring in place to get the signals back there where you need them. Start by checking for missing relays. It is often the case they simply don't install them. This info can be found in your owner's manual. If this does not work you can contact the dealer to see if there is a harness...

This will plug inline with your 7-way and will provide you with an additional 4-way for the light bar. I attached a page that has all of our under tailgate lights we offer that...

• Trailer Hitch Receiver For a 2014 Toyota Tundra Without Factory Receiver For Towing a Small Boat
  The Curt Trailer Hitch Receiver # 13198 will allow you to add a receiver to your 2014 Toyota Tundra which did not come with a factory hitch. I do see you should still have a factory 4-way tucked up behind your bumper so this will allow you to connect to most small trailers. If you cannot locate it then it may have been removed and you would need the Harness # HM11141835 to plug into the factory harness.
