2005 Toyota RAV4 - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Toyota RAV4 with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 5 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area.


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


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

It was the easiest wiring any trailer that I have ever done. Didn't have to cut or splice any wires, just unplug tail light wires and plug in the wiring harness. It took me 10 minutes for complete installation.

This product Item: C55307 literally took me 18minutes and 48seconds to install on my 2002 Toyota RAV4. I opened the back door, set my trim removal tools, cordless drill and 12v DC circuit tester on the ground. I removed my phone from my back pocket and started the timer. I removed the trim as per the video. Installed the wiring kit as directed. Tested each circuit as suggested before reinstalling the trim. Reinstalled the trim and closed the back door 18m 48s. etrailer has my business for sure. Top notch outfit.

The instructions were grossly inadequate to comfortably install the wire harness. Because I am experienced in automotive electrics I will figure it out. The harness appears well thought out and will avoid taps, but the instructions as to how to get behind the taillights to connect them in were a puzzle.

We do have an installation video on a similar year RAV-4 if you would like to check it out.

I received my trailer hitch and wiring harness as predicted by the shipping estimates for free shipping. The installation of both hitch and wiring harness was very simple. Hitch installed in 20 minutes and harness 30 minutes. Had hooked up to my trailer and on the road with in ~hour. Thanks for the quality product!

Installation when smooth an easy in our RAV4, a snap as they say. The hardest part was partially taking out the rear quarter panels to access the factory wiring. I would advise NOT sticking down the black distribution block with the two sided tape until you have finally placed and secured the wiring.

The web page was so easy to navigate even for a senior I was able to be sure I got the right wiring harness made for my RAV4. Made it a simple install and all the lights work perfect. Thanks for helping me get it right the first time.

I really appreciate the effective way everything has been thought out for the customer. From the video to how the product is packaged. I ordered this wiring kit along with the tow bar. Both items arrived at the same time. The tow bar took me 14 minutes to install (no power or pneumatic tools). The wiring kit took me about 15 minutes as well. I truley appreciate finding this package at a good price. I will definately be recommending etrailer.

Excellent product fit like a glove I am 70 years old and installed this curt hitch by myself In about 30 mins, the curt wiring harness took longer because I wanted to make sure I didn’t pinch any wires.. but was a pleasure to complete, no problems.. will be able to now pull a small yard trailer..

Everyone was very helpful and the hitch arrived in a very timely manner. I found it very easy to install. I still have to tackle the wiring harness. So far I am very satisfied.

Plug and play wire harness, but the wires are on the short side. It would have been nice if there was another 1' to 2' of wires to cross from the passenger side to the driver side (that would have helped , but I was still able to make it work).

  • Cleaning Out Corroded Weldnuts to Install a Trailer Hitch on a 2005 Toyota RAV4 or Any Vehicle
    Instead of tapping new threads, which should be a last resort only, you can clean out the weldnuts on your 2005 Toyota RAV4. This will take a little extra time and some elbow grease but it is the best way to ensure no damage is done to the vehicle weldnuts. You will need a stiff wire brush that fits into the holes and some spray lubricant like WD40 or PB Blaster. Liberally spray in the holes and let it soak for about 15 minutes. Then go at it with the wire brush. You may need to repeat...

  • Will the Curt Circuit Protected Converter # C56175 Fit a 2001 Toyota RAV4
    Yes, the Curt Circuit Protected Converter, # C56175, will fit your 2001 Toyota RAV4. There are two reasons why you do not see this harness in Curts fit guide. First, Curt offers a custom T-connector wiring harness, part # C55307, for your vehicle so Curt will not list a splice-in harness. Before Curt made the T-connector harness, the harness you referenced was the recommended wiring harness. Second, this harness can be used on most vehicles that have separate, rather than combined, tail...

It fits the RAV4 starting with the 2001 model year. The correct Curt 4-pole harness for the 1999 RAV4 is Curt # C55486 or one of the other two options shown on the linked page.

    Correct, the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C55307 is a confirmed fit for a 2005 Toyota RAV4. The Curt T-Connector simply plugs in behind the tail light housings making for a plug and play installation. I have attached a sample install video for you as well.

  • Should 4-Pole Wiring Harness Be Kept Inside Vehicle When Not in Use
    Unless you tow almost every day I recommend keeping your 4-pole trailer connector inside the vehicle where it is protected from corrosion and damage. Many wiring issues can arise from corrosion and so it is best to save yourself that potential hassle by keeping the harness out of harm's way as much as possible. The various harnesses for your RAV4, Curt harness # C55307, Tekonsha # 118389 and Hopkins # 33465, all have a protective cover for their 4-pole plug, but I still recommend keeping...

  • Trailer Wiring Harness for a 1999Toyota RAV4
    The Curt trailer wiring harness # C55307 fits 2001 to 2005 Toyota RAV4 models but it will not fit a 1999 RAV4. For your 1999 RAV4 you would need to use # C55486. Or you could use harness # 118388. And a third option is Hopkins harness # 43455. Out of these three options I recommend Tow Ready harness # 118388 since they tend to be the most reliable.
