• Upgrading Trailer Wiring on a 2002 Toyota Sequoia from a Factory 4 Wire to a 7 Wire RV Plug
  To upgrade your 2002 Toyota Sequoia to a 7-Way RV style connector you will need to add a 4-Way to 7-Way adapter, like the Adapter 4 Pole to 7 Pole and 4 Pole, item # 37185. There is a 4-Way connector on the back of the adapter that you plug your existing 4-Way connector into, then you will need to hard wire the remaining wires. There is not a factory style 7-Way connector available for your model. The black is for 12 volt power and is connected to the vehicle battery through a 40 amp circuit...

• Brake Controller and Install Recommendation for a 2002 Toyota Sequoia
  You will need to start with a 4-way (if you do not have one). For that you would want the # C55246. 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 the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. To find the stoplight switch you will need to use a circuit tester like part # 3808 to test all of the wires at the...

• 5-Pole Flat Trailer Connector for 2001 Toyota Sequoia
  We do have options for you to wire your 2001 Toyota Sequoia, but the harness you mentioned will not work. If you have a factory Tow Package, we have a Curt harness, product # C55246, that is very easy to install. I've linked a video of the installation for you. If your vehicle does not have the factory Tow Package, you will need to use a universal kit. The kit by Tekonsha, product # 119178KIT is a good option. I've linked a video review for this kit. It's more difficult to install and...

• How to Install Trailer Brake Controller on 2001 Toyota Sequoia Without Factory Brake Control Port
  We can help you with installation of a brake controller like the reliable and popular Prodigy P3 # 90195 on your 2001 Toyota Sequoia. You will need to have a working 4-pole trailer wiring harness on your truck in order to start the installation. If you need one you can use # C55246 if your truck has the factory tow package with a square connector (see photo). if not, then you'll use a universal 4-pole harness kit such as # 119178KIT. All you'll need to add apart from the controller itself...

• Recommended 7-Way Trailer Connector for a 2002 Toyota Sequoia
  I was not able to reference "633385" on our site. However, after further research it appears that this part number is in reference to a 7-way trailer connector. If this is the case, then the only way to install a 7-way trailer connector on the rear of your 2002 Toyota Sequoia would be to use a combination of the Curt Custom Vehicle Wiring Harness part # C55246 and the Universal Installation Kit for Trailer Brake Controller part # ETBC7. If you already have a 4-way trailer connector, then...

• 4-Way Trailer Wiring Harness for a 2002 Toyota Tundra
  Wiring harness # C55246 is not a confirmed fit for your 2002 Toyota Tundra but we do have wiring harnesses that will work. To add a 4-Way you can use # C55378, # 118378, or # HM43375. If it were me, I would go with # 118378 because it is the best value and we hear about fewer problems with the Tekonsha brand. I have linked a video showing an example installation for you.

• Trailer Wiring Harness for a 2002 Toyota Sequoia without Factory Tow Package
  It is possible that all 2002 Toyota Sequoia models were pre-wired for a trailer connector. You can look to see if yours has the factory plug to install a harness such as # C55246. It will be located on the driver's side plugged into a dummy plug behind the rear bumper. I included a picture that should help identify it. If that plug is not present on your Sequoia or it does not have any power then you can hardwire in a 4-Way flat trailer connector. I recommend ZCI harness # 119250KIT because...

• Hitch Recommendation for a 2001 Toyota Sequoia
  The Curt Hitch part # C13900 is a multi-fit hitch for many different vehicles but it is not a confirmed fit for the 2001 Toyota Sequoia. The multi-fit hitch requires drilling to fit. The custom fit Curt hitch for the 2001 Toyota Sequoia is part # 13440 and does not require drilling to install. I have attached an installation video of this hitch for your reference. If you are using the hitch to tow a trailer, the tongue weight capacity of the custom fit Curt hitch is 500 lbs so it allows...

• Troubleshooting 4-Pole Connector Not Testing for Turn Signals on 2002 Toyota Sequoia
  If your 2002 Toyota Sequoia has a factory trailer tow package wiring that the 4-Pole connector is plugged in to, you can test the factory wiring to ensure it is functioning properly. Unplugging the 4-Pole connector will provide access to the pins for the factory wiring. You will want to use a circuit tester, like # PTW2993, to test the pins on the factory wiring. They should test for taillights, right stop and turn, and left stop and turn. I have attached a video on testing with the...

• Trailer Brake Controller Installation on 2002 Toyota Sequoia
  You will not need to tap into any brake lines on your Sequoia. How you'll proceed will depend on whether the trailer has brakes and which trailer connector it has. I'll assume the trailer has electric brakes and is equipped with a 7-way trailer connector which is what's typically found on a trailer with brakes. If your trailer has electric brakes, and you want them to actuate, you'll need to install a brake controller. I'd recommend a proportional controller like the Tekonsha Prodigy P2,...

• Recommendation for Converting a 4-Way Plug to 7-Way Plug on a 2010 Toyota Tacoma TRD
  Good news! I can help you wire up your 2010 Toyota Tacoma TRD from a 4-way to a 7-way for your trailer. I recommend using the # ETBC7 wiring harness to transform your aftermarket 4-way harness into a 7-way connector. This will allow you to plug in your current 4-pole and then run the additional wire functions to your vehicle for the 7-way. Since you are not in need of the brake controller function, you will only want to mount the ground wire in addition to plugging in your current 4-way....

• Recommended Brake Controller and Wiring for a 2002 Toyota Sequoia without Factory Tow Package
  Great news! I can help you setup your 2002 Toyota Sequoia with a brake controller so you can tow your Terry RV. For a brake controller, I recommend the Tekonsha P3 # 90195, because of its easy user interface. The P3 is a proportional brake controller which means it senses how the tow vehicle is slowing or stopping and applies the trailer's brakes with the same intensity. It also has a full display screen instead of codes that need deciphering. The Tekonsha P2 # 90885 is like the P3's...

• Trailer Lights Working Intermittently when Connected to a 2002 Toyota Sequoia
  Since the trailer wiring harness on your 2002 Toyota Sequoia is working properly the issue must be on the trailer. There are multiple grounds for trailer lights so it could still be a ground issue. The lights working intermittently suggests a ground issue, corroded connector, or break in the wiring, but not really a short. Make sure the trailer side connector is clean and free of corrosion inside, if applicable, and outside on the pins. The main trailer connector ground and the grounds...

• Recommended Wiring Harness For 2001 Toyota Sequoia Without Factory Trailer Hitch Receiver
  For your 2001 Toyota Sequoia I recommend the Curt Wiring Harness # C55246 you were looking at as it will plug into the factory trailer connector port underneath the rear bumper of your vehicle. If you have not already decided on a trailer hitch receiver, I recommend going with the Curt # 13440 as it is a quality hitch made right here in the USA with a 500lb tongue weight rating and 5000lb trailer weight rating making it a great option for towing a trailer. To complete your towing setup,...

• Adding a 7-Way Connector to a 2001 Toyota Sequoia
  The 2001 Toyota Sequoia with factory tow package would require you to first plug in a 4-way such as # C55246 as you can see from the accompanying photo. From there you would be able to add a 7-way with adapter # 30717, which will plug into the 4-way. I've added links to video reviews of these parts for you to take a look at.
