• Recommended 7-Way Trailer Connector And Brake Controller For 2005 Toyota Tundra
  For your 2005 Toyota Tundra, I recommend the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires, # ETBC7. This kit will use your existing 4 way and will allow you to connect the reverse wire, 12V power wire, and brake controller wire to make a 7-way and 4-way accessible connection. This kit includes the wire, the circuit breakers, and all the connections needed. I've attached a couple videos to help. The # 20137 plug and play is only...

• How To Determine Functions of 2005 Toyota 4Runner OEM Trailer Wiring Harness
  In order to know what wires on the new vehicle-end connector will connect to which wires on the OEM harness, you will want to use a circuit tester, like # 40376, to test the wires in the OEM harness for their functions. Once you know the wires functions, you will want to connect them to the new vehicle-end trailer connector by function. It is easiest to test the wires functions if you have a helper who can sit in the driver's seat and activate the turn signals and other lights as needed...

• Using Hopkins # HM43385 or Tow Ready # 20137 Replacement 7-Way Connector on 2006 Toyota Tundra
  There is a difference between the Tow Ready # 20137 and the Hopkins # HM43385. Each trailer connector uses two plugs that insert into the factory connections, but the 3 pin plug on each is wired DIFFERENTLY. For some unknown reason, Toyota wired the plugs differently on some vehicles. If you look at the photo I've edited for you, you can see the difference. The replacement 7-way you use will depend on how your 3-pin plug on your Tundra is wired. Use a circuit tester like # 40376, and...

• 7-Way and 4-Way Trailer Wiring Connector Recommendation for 2010 Toyota Sequoia
  Sounds like your 2010 Toyota Sequoia has a standard 7-way on it and you are looking for something like the part # HM40975 which would plug in as a replacement and give you a 7-way and a 4-way. If you have a round connector like what's in the picture I attached that runs to your current connector (this is the standard connector seen on nearly all vehicles), the # HM40975 would be exactly what you need. If instead you have a flat 4-way connector on your vehicle you instead would want the...

• Adding a 7-Way Trailer Connector to a 2004 Toyota Sequoia without Factory 7-Way
  First, if your 2004 Toyota Sequoia did not come with a factory installed 7-Way trailer connector then replacement connector # 20137 is not going to fit. The connection points will not be present to plug it in. If no factory harness is present you will need to hardwire in a 7-Way. To hardwire in a 7-Way you will need 2 parts, 4-Way flat harness # 46365. Then to add a 7-Way you will need # ETBC7. I have included links that explain the ETBC7 installation for you. It is odd that your...

• Installing a Brake Controller on 2005 Toyota Tundra
  The factory installed brake controller connector should be a white plug located on the left side under the drivers side dash on your 2005 Toyota Tundra Dual Cab. I have included a photo and a video that shows the location of the plug on another Toyota Tundra at the 8 second mark. This plug may not be there if your vehicle did not come with the factory tow package. The Multi-Plug, # 20137, is designed as a replacement if your vehicle came with a factory tow package that included the...

• Will the Tow Ready Multi-Plug # 20137 Replace a Powered Converter on 2003 Lexus GX470
  Tow Ready tells me that most likely the 20137 will work on your Lexus GX470. You can confirm this before purchasing by having a helper activate the various lighting functions while you test the connectors under the vehicle with a circuit tester like part # 40376. Activate the left turn signal, and test the various pins on the connector. You should locate one pin that will make the tester light up. Do the same with the right turn and the running lights. If this checks out, the 20137...

• Wiring Harness for 2006 Toyota Tundra With Tow Package
  From the picture that you sent, it looks like your 2006 Toyota Tundra is equipped with a factory tow package. All you will need to do is use the Tekonsha Replacement Multi-Plug Trailer Connector # 20137. This will plug directly into the connectors that you found and will give you a fully functional 4-Way and 7-Way wiring harness at the back of your Tundra. You can also use a No-Drill Mount Bracket, Short # 18140, or Long # C57202, for an easy installation of the harness to your trailer...

• Replacement 7-Way Recommendation for a 2006 Toyota Tacoma with Factory 7-Way
  I have a solution for you, but it will require a little wiring and it is not the Trailer Wiring Harness part # 20137. There currently isn't a plug and play replacement 7-way available for your 2006 Toyota Tacoma so the best recommendation I can make would be to get the 7-Way Prewired Car Connector part # 20023. You will need to remove your current 7-way and bracket and cut the wires from the harness and wire them by function to the wires of the # 20023. I attached a picture that shows...

• What Parts are Need to Add a 7-Way Trailer Connector to a 2001 Toyota Tundra
  I do have a solution for you. In order to add a 7-Way wiring harness to your 2001 Toyota Tundra, you will need to start by adding a 4-Way, # 118378, if you need one. I have included a link to the installation instructions for this harness for you to view. With a 4-Way installed (or using an existing 4-Way if applicable) you will then need to install a 4 and 7 Way Installation Kit, # ETBC7. This kit includes everything you will need to install a functioning 7-Way on your truck. I have...

• Recommended Replacement 4-Way and 7-Way Wiring for a 2003 Toyota Tundra Without a Tow Package
  The # 20137 would not be a fit for your 2003 Toyota Tundra, as it will only work on models with the factory tow package. In order to first replace the 4-Way plug, you will need to use a hardwire kit, like part # 119179KIT. The # 119179KIT wiring kit is a universal application, so vehicle specific instructions are not available for your Tundra. You will need to use the included circuit tester to determine which wires behind your vehicle taillights are performing which function, and...

• What 7-Way And 4-Way Connector Will Replace Existing 7-Way On 2008 Toyota Tundra With Tow Package
  For your 2008 Toyota Tundra with factory tow package you will need to use the Hopkins Replacement Multi-Tow 7-Way and 4-Way Trailer Connector # HM11143395. This will plug into your factory tow package wiring harness and give you a 7-way and 4-way at the rear of your vehicle. It looks just like the # 20137 picture, but has a different connector for the 2008 to 2010 Toyota Tundra. The Tow Ready Replacement Multi-Plug 7-Way and 4 Pole Trailer Connector, part # 20137, is for the 2003 to...

• Parts Needed to Add a 7-Way Trailer Connector to a 2005 Toyota Tundra
  The Multi-Plug, # 20137, is designed as a replacement if your 2005 Toyota Tundra came with a factory tow package that included the harness from the factory. To add a 7-Way to a truck that did not have the factory tow package, you would first need to install a 4-Way, # 119179KIT. I have included a link to the isntallation details for you to view. This converter will take the separate turn and brake signals on the truck and make them a combined signal for use with the trailer. After...

• Wiring In-Bed Truck Camper Running Lights and 12 Volt Circuit to 2012 Toyota Tacoma
  Tapping into the vehicle's 4-Way trailer connector for running lights will work great. It is the pin next to the ground pin, usually a brown wire. The aftermarket 4-Ways for the 2012 Toyota Tacoma are all going to be circuit protected so you would not have to worry about that circuit causing any trouble with the vehicle wiring. You would not have to use diodes for the 12 volt circuit. What I recommend is 10 gauge wire, # 10-1-1 sold by the foot, and a circuit breaker such as # PK54520...

• How to Find Brake Switch Circuit for Brake Controller Installation without Damaging Wiring
  What you will need to do is use a circuit tester like # PTW2993 to probe all of the wires from the brake switch to determine which one carries 12 volts when the brakes are applied and none when released. The # PTW2993 is designed for probing a wire so that it's function can be determined without damaging the circuit. It basically has a sharp needle that will puncture the insulation of the wire and touch the core to test for voltage. When the tester is removed from the circuit it wouldn't...

Both are designed and have been tested specifically for your vehicle if you have the connectors are the rear of the Sequoia which can be found slightly towards the driver's side. I've attached a picture of the connectors on the harnesses. The Tekonsha harness measures about 16 from the back of the 7-way connector to the end of the connectors that mate with...

• Troubleshooting Trailer Turn Signals Not Functioning After Install of ETBC7
  Unplug the 4-way of your vehicle and check the pins of it. Most likely there is corrosion on a few of the pins that will need to get cleaned off. Nearly everytime this problem comes up the issue is just corrosion that needs to be cleaned off. Or, just connectors that aren't perfectly seated together. If that doesn't fix the problem test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied....

• 4-Way Recommendations for a 2005 Toyota Tundra Towing a Small Kayak Trailer
  For just taillight functions all you would need would be a 4-way trailer wiring setup. Which if you don't have a 4-way on your 2005 Toyota Tundra you could install the part # 20137 and you would end up with both a 4-way and a 7-way at the rear of your vehicle. If you are looking for a connector for your trailer with a lead you would want the # A35W42B which is a 4-way with 35 feet of 4-way wiring.

• Only Right Turn/Brake Lights Work After Installing Trailer Wiring Harness on a 2003 Toyota Sequoia
  In order for the trailer connector # 20137 to work, your 2003 Toyota Sequoia would need to have been equipped with a factory 7-Way trailer connector. If it never had a factory 7-Way, even though the connection points are there, the harness will not be fully functional. You may be able to take the vehicle to a dealer to have the missing components installed to make it fully functional. Also it is possible that some relays or fuses would need to be installed in order for the connector to...

• Troubleshooting Trailer Running Lights After Installation of Light Kit
  Often when trailer lights funtion except the tail or running lights the issue is a bad ground. Unlike stop and turn lights that come on an off, running lights remain on and this means they pull more current. A weak ground may still allow those other functions to operate and reveal itself only when your load draws higher current, such as when the taillights are on. Check the main white ground wire on both the vehicle harness and the trailer harness. (Focus on the vehicle since the trailer...

If you have the factory connections but are missing the trailer connector, then you would use the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM43385 or the Replacement Multi-Plug 7-Way and 4 Pole Trailer Connector # 20137.

• Recommended Wiring Harness for 2006 Toyota 4Runner
  We do have replacement connectors available for your 2006 Toyota 4Runner, all of which will provide both a 7-Way and 4-Way flat connector. If you have a 3-pin plug and a 4-pin plug at the rear of your vehicle, then you will need either the Tekonsha # 20137 or the Hopkins # HM43385, depending on how they are pinned. The issue is that Toyota wired many of their vehicle models during these years in two different ways. You will need to match the wiring with the diagram on the 3-pin connector,...

  Your 2006 Lexus GX 470 is part of this vehicle's first generation, which ran through 2009.

• Replacement 7-Way and 4-Way Trailer Connector for a 2007 Toyota Tundra
  We do have a replacement 7-way and 4-way trailer connector for the 2007 Toyota Tundra, but before we can determine which harness will work for your truck, we will need to know what type of plugs your trucks tow package wiring requires and how the connectors are wired. Unfortunately, Toyota decided to wire this truck a number of different ways. The Tundra had a generation change between 2006 and 2007 and this caused some discrepancies in the wiring. Your factory 4-way and 7-way trailer...

  I have included a picture for you that will help. On your 2004 Toyota Tundra, find the connector under the truck that # HM43385 would plug into. Then use a circuit tester, # 40376 if you do not have one, to test the pins on the 3-pin part. The pins should be a mirror opposite of what you see in the picture. If they are not you would need to use # 20137 instead. The wiring harness part of either of these connectors should be plenty long enough to mount the connector where you need to....
