My 2016 Tundra already had the wiring harness so I only needed the socket. The harness on the Tundra just had a plastic cap that had to be removed and the socket clipped right in place. Easy.

  • Installation of # HM11141835 Wiring Harness
    The Hopkins trailer wiring harness, part # HM11141835, does not need a fuse for installation. It plugs directly into a connector near the truck's spare tire behind the rear bumper. I've linked the install details for you. The # HM11141835 harness fits the Toyota Tundra from 2010 to 2018.

  • Parts Recommendation to Install a 4-way in a 2012 Toyota Tundra
    Yes, the # HM11141835 that you referenced has been confirmed to fit your 2012 Toyota Tundra and would install in the connectors you have found behind the bumper. Or, if you have a factory 7-way and you want to keep it functional and have an additional 4-way for the light bar you could use the # 118384 instead. 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...

  • Replacing a 7-Way with a 7 and 4-Way on a 2014 Toyota Tundra
    Trailer wiring harness # HM11141835 is designed as a replacement for a 2014 Toyota Tundra that came with a factory 4-Way. There isn't an additional connector if your truck already has the 7-Way. A simple solution would be to replace the factory 7-Way with # HM11143395 which is both a 7-Way and a 4-Way so you would have access to both types of connectors.

  • 4-Way Trailer Wiring Harness Recommendation for a 2016 Toyota Tundra
    If you have a factory trailer wiring connector you could use the part # HM11141835 as a way to install a 4-way easily. Or if you have the factory 7-way connector (which most likely you do), you could use the part # C55384 to splice a 4-way easily into the 7-way wiring harness.

  • 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...

  • Recommended Wiring And Connectors To Add A 7-Way With A Brake Controller To A 2016 Toyota Tundra
    For your 2016 Toyota Tundra, some of the wiring is run for your vehicle even though you don't have the factory installed trailer package. We first need to get the Hopkins Plug in Simple Vehicle Wiring Harness with 4 Pole Trailer Connector, # HM11141835. This will clip into place at the rear of the truck using the included dielectric grease. Then utilizing this 4-Way connection, we will need the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge...

    For your 2016 Toyota Tundra SR5, because you don't have a tow package we will start at the beginning. If you don't have a working 4-way flat trailer connector, then let's start there. I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM11141835. Once you have the 4-way, then you can use the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7. This kit will allow you to plug in the 4-way and then...

Next, we will want the 7 way plug that fits in that knockout you mentioned. I suggest the Pollak 7-Pole and 4-Pole Trailer Connector Sockets w/ Mounting Bracket and Wiring - Vehicle End, # HM40975-11998, and splicing this into your 4-way. This will give you the 4-way trailer function with a factory look. Then...

  • Tekonsha Brake Controller Wiring Adapter for 2014 Toyota Tundra
    The Tekonsha Plug-In Wiring Adapter # 3040-P is the correct harness to install a Tekonsha brake controller in a 2014 Toyota Tundra that is equipped with the factory 7-way trailer connector. This connects to an under-dash port as shown in the linked video. If your truck does not have a factory trailer connector then you will need instead a brake controller install kit # ETBC7 and also a 4-pole harness # HM11141835.

    If your 2014 Toyota Tundra has a the factory 7-way trailer connector installed, then you will need to use # 3040-P wiring harness to plug in to the factory plug. The factory plug is located under the driver's side dash behind the kick panel in the same are where the emergency brake is located.

  • Trailer Wiring Recommendation for 2014 Toyota Tundra
    The 2014 Toyota Tundra should at least come with a factory 4-way, but if it's not present the part # HM11141835 would be what you need. Now if your trailer does not have brakes and you need a 7-way instead all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

  • Wiring Needed To Use Rampage Light Strip On 2012 Toyota Tundra
    The Rampage SuperBrite LED Tailgate Light Bar part # RA960134 does connect to a 4-pole flat trailer connector on the Tundra. For that I recommend Curt T-Connector Vehicle Wiring Harness for Factory Tow Package part # C55774 which will allow you to plug into the factory tow port under the bumper and gives you a 7-way plug and a 4-pole flat to plug your light strip part # RA960134 into. You can use both the 4-pole and 7-way functions at the same time as long as you don't overload the circuit...

    If you have a factory 4-way on your 2008 Toyota Tundra you will likely have a short in the factory wiring. You should have a connector like the Hopkins Plug-In Simple Vehicle Wiring Harness # HM11141835 which you can remove to verify if the short is on the factory harness. A Test Light # PTW2993 can be used to check the wiring for shorts and test the pins for the 4-way harness on the factory side of the main harness. Otherwise you likely have a harness like the Upgraded Modulite Vehicle...

  • Installing Tekonsha Prodigy P3 Brake Controller # 90195 on 2014 Tundra Without Brake Control Port
    Your 2014 Toyota Tundra with a factory 7-way trailer connector should have an under-dash brake control port above the kick panel and to the left of the emergency brake pedal. Sometimes these harnesses may be taped up to other wiring or tucked out of the way. If you cannot find the port you can still do a hard-wired installation for your Prodigy P3 controller # 90195. If you find the port you can use part # 3040-P to plug in the P3. Please refer to the linked video. If you cannot find...

    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. If not, then you would need to hardwire the controller. You will need to start with a 4-way (if you do not have one). For that you would want the # HM11141835. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want...

  • Brake Controller Recommendation for 2013 Toyota Tundra
    For a brake controller for your 2013 Toyota Tundra I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well. If your truck...

  • Recommended Brake Controller For 2013 Toyota Tundra
    Brake controllers are not vehicle specific. A wide variety of brake controllers will work for your 2013 Toyota Tundra. If you have a factory 7-way, then there are vehicle specific wiring harnesses to make installation easier. You can find those using our fit guide. For your vehicle, I recommend the Tekonsha Prodigy P3 # 90195. This is a proportional brake controller that in my opinion is the best on the market. It has an easy to read LCD screen with no code deciphering. The information...

  • Recommended Wiring For Tekonsha Prodigy P3 in 2013 Toyota Tundra
    For your 2013 Toyota Tundra, if you already have a factory 7-way connector at your bumper you will simply want # 3040-P to wire the Tekonsha Prodigy P3 # 90195. This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. If you have a factory 4-way, then that harness will not work and you want the # ETBC7 instead....

  • How to Add Second Wiring Harness to 2018 Toyota Tundra to Power Tailgate Light Bar
    If your 2018 Tundra has wiring that uses a round U.S. Car type connector (like the item shown in the linked photo) then you can easily piggyback a second wiring harness and have both remain active. Most tailgate light bars use a 4-pole flat connector so if this is what you have all you need is part # 118384 which will simply plug in between your 7-way socket and the U.S. Car connector that connects to the back of it. Please check out the linked install video. I strongly recommend using...

  • How to Trouble Shoot Brake and Turn Signals Not Working On a Trailer
    This can be caused by a few things. First and foremost, you will need to check a couple fuses to make sure they are still in good condition. Under the hood of your 2018 Toyota Tundra, you will want to check the fuses in positions 6 and 37. Then you will need to check the cluster under the instrument panel for fuses 20 and 22. These can be confirmed in your owner's manual, but these are responsible for the towing lights. If one or more have blown, it will definitely cause the issue you are...

  • How to Connect Brake Output Circuit on a 2012 Toyota Tundra When Installing Brake Controller
    If the # 3040-P harness is powering up the brake controller you are looking to install in your 2012 Toyota Tundra that would mean that you would only need to run the blue wire of the controller (the one you traced) back to a 7-way at the rear of it. If you need a 7-way you would want the part # 37185. You would need to connect the blue wire of this connector to the blue wire you traced earlier with 10 gauge wire like part # 10-1-1 that is sold by the foot. Normally for the 2012 Toyota...

    The Rampage SuperBrite LED Tailgate Light Bar part # RA960137 is very simple to install and will only require one hardwire connection. I have attached the installation instructions for you below but to summarize, you will first want to plug the 4-way trailer connector on the light bar into the 4-way trailer connector on the vehicle. If you don't already have a 4-way trailer connector you can use part # HM11141835. I also highly recommend using a bit of part # 11755 before mating the two...

  • Recommended Towing Equipment for towing a 8,800 lb Dry Trailer with a 2014 Toyota Tundra
    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. If you don't already have towing equipment (or a brake controller) then I have some recommendations for you. The Draw-Tite Ultra...
