Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

Trailer hitch and wiring harness I ordered for my 2002 Highlander fit and worked perfectly.lt came in perfect condition in only 3 days.
Will definitely order from etrailer again.



by:

Straightforward install. Just pop the plug cover on the vehicle connector, plug the trailer connector and you're good to go.



by:

I always get my trailer hitches and supplies from etrailer and have never been disappointed. The quality is good, price is right and they ship it right out!



by:
2001 Lexus RX 300

Wow! What a great experience dealing with etrailer.com. I received the hitch and wiring harness and it took longer to pull the staples out of the box than it did to install all of the parts. It is all in now and waiting to hook up the boat trailer and do some fishing. I can't say enough as to how pleased I am. If backing up the trailer goes as well as the installation, I will be grinning for the rest of my life.

I absolutely love it, the best accessory I ahve added to my Vehicle!



by:

This product was shipped to me with two wires reversed. It cost me $[XX] for the Toyota dealer to troubleshoot the problem and find that two wires were reversed. I am not happy.



by:

Ordered on Saturday, shipped on Saturday and arrived on Wednesday. The hitch and wire harness were easy to install - from start to finish took a little over 1 hour. All holes lined up with no adjustments. Looks Great!



by:
2001 Lexus RX 300

Extremely easy to install, even came with a fuse for the trailer lights!
Highly recommended doesn't get much easier to install



by:
2002 Lexus RX 300

Perfect fit! Even at 21 years old the Lexus was ready to go with no difficulties and this tow hitch lined up perfectly and flawlessly. Fluid filmed the metals before encasing them.



by:

Replacement for my 2002 4Runner. After 20 yrs and a splice you’d have to imagine there would be some degradation to the OEM harness. The OEM harness had gotten pretty finicky. This was a direct plug and play kit. It plugs in near the driver’s rear corner, route it, a few zip ties and everything is G2G.

It didn’t fit my vehicle, 2010 Lexus LX 570 even after research on forums and looking for the connector on the passenger side.

This product is intended as a replacement piece for your factory 4 way flat.

Product was delivered on time and included in the box with my new DrawTite hitch. I'm looking forward to installing my hitch and electrical harness this weekend. Hitch was boxed well - no damage. Thank you.



by:
2003 Toyota Highlander

Fit right just what I wanted arrived 2 days earlier than expected



by:

The wiring harness was a good thing ,easy to install came the instructions it just plugged right in, zip tie it and was done thank you



by:
2002 Toyota4Runner

Very fast shipping exactly what I was looking for easy instill took 10 min but would have taking 5 min if I got the bracket for the 4 pin to mount but I didn't had to reuse the old one will and already recommend etrailer.com to friends



by:

Harness itself is extremely high quality as well as the connector for it. I only gave it 4 stars because it is about 1 foot longer than it really needs to be for the car. Not s big deal but since it’s vehicle specific I’d like it to be a little shorter to fit the application better. Overall I’d recommend though, it’s high quality and works great!



by:

Came quickly. No damage. Hitch went on without a hitch. Electrical connection was very easy to install. Works great!



by:
Toyota Highlander

Part was delivered quickly and in good condition. Fit was perfect and did what I needed it to do on a Highlander with a factory tow package.



by:
2002 Toyota Highlander

super easy to install, so glad my Toyota was pre-wired. Easy to tell if you open the spare tire area you will see a blue towing controller box.



by:

Perfect replacement fit for an OEM part that had seen better days. 3 minute install.



by:

Simple plug and play. Couldn’t ask for anything simpler



by:
Toyota

Ditto on the lighting cable. Curt and Toyota made it easy.



by:

After a year no issues and is still in great shape pretty good product

  • Product Comparison Between Vehicle Wiring Harness C55245 vs 118245 for a 2001 Lexus LX 470
    I can help compare the # C55245 and the # 118245. These two wiring harnesses are designed to do the same job for wiring up your 2001 Lexus LX-470 the only real difference is the manufacture that they are distributed from. The # 118245 is designed and distributed by Tow Ready a company owned by Cequent Manufacturing and the # C55245 is designed and distributed by Curt Manufacturing. Both harnesses plug in the same way and provide a 4 pole connector for your vehicle end. For your vehicle...

  • Trailer Wiring Harness for 2002 Toyota Highlander
    Your photo did not come through to us with your question, but we appreciate that effort! The Curt Custom Fit Vehicle Wiring Kit you referenced, part # C55245, is intended for vehicles that have the factory tow package installed. The connector that mates to the OEM wiring on your Highlander is indeed a 4-pin square type as you note. This connector is typically found at the rear underside of the vehicle. It may be that your truck has been modified (or that Toyota made a running change) but...

  • Does Wiring Harness for 2001 Lexus RX 300 for Factory Tow Package Require Programming
    The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55245 does not require any programming as it is a simple replacement for the factory 4-flat on your 2001 Lexus RX 300; it does require the fuse be put into the location shown in the accompanying photo I added from the linked installation instructions. If you did not already have the factory 4-flat then this wiring harness would not work and you would instead need the Vehicle Wiring Harness # C59496.

  • Trailer Lights Wont Work After Wiring Harness Install on a 2001 Lexus RX300
    There are two types of wiring harnesses for your 2001 Lexus RX300, one if you have the factory tow package and one if you do not have the factory tow package. In order to determine if you have the factory tow package you would need to call the manufacturer and provide them with your VIN as they will be the only ones that will know whether or not the circuits are active for the factory tow package. What we run into is that customers will find the factory tow plug on their vehicle and then...

  • Why Wont Trailer Wiring Harness Work on 2002 Lexus LX 470
    There are 2 different Curt trailer wiring harnesses for your 2002 Lexus LX 470. If the vehicle did not come with the factory tow package then you would need # C59236. If it does have the factory tow package you would use # C55245. If you are not sure, have a Lexus dealer run the VIN number to tell you how it is equipped. Please note that even if a model has the connection point for harness # C55245 it may not be active if the vehicle does not have the factory tow package. You can also...

  • How To Determine If 2003 Toyota Highlander Has The Factory Tow Package
    if your 2003 Toyota Highlander has a tow package plug located in the driver's side rear cargo area under the floor (see instructions for installing Item # 118413 on where to look) then your Highlander has the tow package. If you find a plug, use a circuit tester like Item # PTW2993 to check to see if it is active. If you do not find a plug or the one you find is not active, then you do not have a tow package. Another way to find out is to contact your local Toyota dealer, give them...

    Yes, we have the wiring harness and you can order it in addition to the item # C26VV hitch for your 2024 Toyota Grand Highlander. Whether you have the plug and play connectors will depend on if your Highlander has the towing package. If you have the tow package you will need the Curt item # C55245.
