CURT Custom Fit Vehicle Wiring - C55486

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

Quickly and easily install a 4-way trailer connector on your vehicle 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.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your 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.

Excellent product! This was the only harness that I could find that was truly plug and play. No splicing required. I went ahead and bought a trailer light kit from them for my 5x8 trailer. Shipping was very quick. I’d give them a sixth star just for that if I could.

Received item just a little after the noon hour and had installed (solo) and wiring harness finished before 5 pm the same day. Everything fit and works perfectly. Had been contemplating a trailer hitch for my old 1997 Toyota RAV4 for awhile but thought it would cost too much. This set up was perfect and much less than I expected or was willing to pay.

Great, once I figured out that my vehicle would not power standard lights. Switched to LED and everything worked out fine.



by:

Still working great a year later!



by:

Have since sold the Vehicle I put this harness on. But used it to pull a trailer on a camping trip and it worked good. Had to extend the back tail light Wire because there wasn’t enough wire so that’s my only complaint. Other than that it worked great



by:

Installed easily. Would have been nice if yellow lead was longer to allow for a better placement of receiver box for longer lead to trailer. Also, not sure if it’s my vehicle (1999 Toyota RAV4) or the cables, but the hazards and most lighting can’t be seen without the car’s engine on.
etrailer was great with fast shipping and accuracy with order.

1997 Toyota RAV4

I ordered this wiring kit with a hitch for my 97 Toyota RAV4. Super easy plug n play setup. Took me about 20 minutes but most of that time was taking out screws. No cutting and taping anything which made it super easy!!!



by:

The wiring harness was easy to install. It works great when I pull my jet ski trailer.



by:
1997 Toyota RAV4

Seams fine and does the job, but taking off 2 stars because the wiring for the left side is too short to route under the plastic step plate and instead would need to go unprotected under the rear carpet.



by:
1999 Toyota RAV4

Fit and finish are perfect. 10 minutes for hitch installation! Trusted seller. Now on to the wiring harness. :-)



by:
1998 Toyota RAV4

This was the perfect replacement part for my 1998 Rav4 and was easy to install.
It works great!

Works fine. A good choice



by:
1998 Toyota RAV4

The only way to install trailer hook up in any vehicle!
Plug and play!



by:

Too short to use properly on a 1997 rav 4. Ultimately the wire does reach across from passenger to driver side, but I found that it needed to be 3-4” longer. Definitely still usable, but a few more inches would be very helpful.



by:
1999 Toyota RAV4

Very easy installation. Start to finish 90 minutes. Works flawlessly.



by:
1998 Toyota RAV4

worked great no cutting plug and play lights as easy as 123.

Very well packaged, fast shipping, everything worked perfectly once I figured out what I was doing wrong. Very happy with this product and the service.

  • Vehicle Lights Do Not Work After Installing Curt T-Connector C55486
    Installing a T-Connector, like the Curt # C55486 should not effect the functionality of the vehicles lights whatsoever. The wiring harness will tee into the vehicles wiring harness, giving you separate wiring for a trailer plug, while leaving all of the connections for your vehicles lights in tact. Please go back and make sure all of the plugs on the T-connector are fully inserted with the locking tabs in place. There are a total of 4 plugs (1 male 1 female each side)on the T-connector...

  • Troubleshooting Curt Custom Fit Vehicle Wiring Harness # C55486 in 1998 Toyota RAV4
    A 4-pole trailer wiring harness like Curt plug-and-play # C55486 interacts with a vehicle's electronics only in three circuits: brake lights, running lights and turn signals. What the harness does is take the separate stop and turn signals from the car and combine them for the trailer, which uses the same light for stop and turn functions. A wiring harness has no direct interaction with other vehicle systems like wipers, radio and air conditioning. It is possible that a damaged harness...

  • No Power to 4-Way on the Curt T-Connector Harness Part # C55486
    When you say you are not getting power to the 4-way on the Curt T-Connector Vehicle Wiring Harness part # C55486, I can only assume you tested each pin with the vehicle running and the signal activated while using a circuit tester? If so then great we can move onto the next step but if not then you will want to do this first. The next step would then be to test the signal wires while they are active just before they enter the converter box. If you have power entering the converter box...

  • How to Pull Apart Tail Light Wiring Connectors to Install Trailer Wiring Harness on 2000 Toyota RAV4
    An easy way to learn and practice how to get the factory tail light connectors apart on your 2000 Toyota RAV4 is to push together and pull apart two compatible ends of the wiring harness # C55486. this is because they have the same locking mechanism as found on the vehicle. Basically, there is a little tab on the side of one of the connectors that locks around a nub on the mating connector. Usually a small flat head screwdriver is all you need to pry up the tab (gently) and pull the connectors...

  • Why Would Trailer Lights Work after Unplugging and Replugging in a Trailer Connector
    It sounds like there might be a little corrosion in your trailer connector and when you unplugged and replugged in the connector you were able to make a good connection. You might inspect the connectors for any corrosion and clean as necessary. That should get rid of the problem. Or the first time you plugged in the connector it was not all the way plugged in. I attached an FAQ article on trailer wiring for you to check out also.

  • Not All Trailer Lights Power On with Trailer Connector C55486 on a 2000 Toyota RAV4
    Since the 4-Way end on the # C55486 harness is working then the issue is most likely a ground on the trailer and/or a dirty connector. Make sure the trailer side connector is clean and free of corrosion. Then make sure the main trailer connector is grounded to a clean and corrosion free bare metal surface. Do the same with each of the trailer lights. If you have an aluminum frame, tilt bed, or folding tongue on the trailer then you will need to run jumper grounds from the lights to the...

  • Recommended Vehicle Wiring Harness for 2000 Toyota Rav4
    For your 2000 Rav4, you will need the Curt T-Connector # C55486. The connectors on the harness will plug inline with the connectors behind your tail light assemblies. You will need to access the rear of each tail light assembly, unplug the factory connector, and plug the wiring harness in between the factory connector and the tail light assembly.

  • Will 4-Pole Connector from Curt Harness # C55486 Fit Tow Ready Mounting Bracket # 18144
    The 4-pole mounting bracket you referenced, part # 18144 from TowReady, will accept the 4-pole trailer connector used on the Curt Custom Fit Vehicle Wiring Harness # C55486. I have requested that this fit information be added to the bracket's product description.

    We can help you with a 4-pole wiring harness for your 1999 Toyota RAV4 but the Curt wiring harness you referenced, part # C55307, is not a fit for your vehicle. 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. Each of these harnesses will plug in inline with your taillight wiring at the back of each taillight assembly. It will be necessary to remove several trim...

  • Recommended Roof Weight Limit of 2010 Toyota RAV4
    My research indicates a roof weight capacity for the 2010 Toyota RAV4 of 102-lbs, and this figure is for a factory roof rack. Always the best place to check is the vehicle owner's manual. The online version of the manual that I reviewed did indicate 102-lbs maximum on page 202. Keep in mind that this limit must include everything on the roof. Let's say you have two kayak carriers that weigh 14-lbs, such as the Rhino-Rack # S512. This 28-lbs counts toward the weight limit as will your two...

  • Troubleshooting Trailer Wiring Harness Installed on 1999 Toyota Rav4
    I'd recommend further confirming that you're not getting any brake lights or turn signals on the trailer connector on the Rav 4 by using a circuit tester like part # PTW2993 on the trailer connector. Activate the brake lights and turn signals while you're testing and check the pins on the connector being fed by the green and yellow wires. If you're not getting signal on the connector, test the green and yellow wires on the INPUT side of the converter. If you have signal going into, but...

  • Does Curt Hitch for 2000 Toyota RAV4 Have Capacity for Towing 1,500 lb Trailer
    Yes, the Curt hitch part # C13524 which fits your 2000 Toyota Rav4 is what you'd want. This has more than enough capacity to tow a trailer weighing up to 1,500 lbs but I also checked and your vehicle has a 1,500 lb towing capacity as well so it would work in that regard as well. For trailer wiring then you'd want the Curt T-Connector part # C55486, which is easy to install and comes with a very reliable converter box. If you wanted to do some towing you might be interested in etrailer...

  • How to Transport a Motorcycle with a 1998 Toyota RAV4
    I have another solution but while the Curt Trailer Hitch Receiver # C13524 you referenced will offer a maximum tongue weight rating of 400lbs, from the research I did on your 1998 Toyota RAV4 it appears that the maximum tongue weight rating is roughly 150lbs. When determining your maximum tongue weight rating you must use the lowest number between your vehicle and trailer hitch receiver. To safely transport your motorcycle behind your vehicle I recommend using a small trailer. You will...

  • 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 will want the Curt # C55486. It is always a good idea to apply a small amount of dielectric grease, # LT37534, to all electrical connections to help prevent corrosion.

  • Recommended Class III Trailer Hitch Receiver For A 1999 Toyota RAV4
    For your 1999 Toyota RAV4, the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13524 is a confirmed fit and is a great hitch that is easy to install and has a nice sturdy square tube design. The rated towing capacity of the hitch is far above your vehicle's rated towing capacity as you stated, but you will be much happier with a Class III hitch. The class 1 hitch will greatly reduce your ability to use accessories and will significantly reduce options for even a ball mount....

  • Troubleshooting Problem with Lights on Trailer Towed By 1998 Toyota RAV4
    It sounds to me like you've covered just about everything. Intermittent wiring problems can drive you nuts, as you're finding out. Does your trailer have a folding, swinging or tilting tongue? Over time, the pivot or hinge can become a bit worn. It'll still work, but it might not be tight enough to provide a continuous ground connection. If this is the case, you can simply make a jumper wire, a short length of wire with a ring terminal on each end, used to bridge the connection. If this...

  • How Does the Curt Trailer Hitch Install on a 1997 Toyota RAV4
    The Curt trailer hitch, # C13524, will bolt to existing holes in the frame of your 1997 Toyota RAV4. The frame has existing weldnuts inside the frame that the hitch hardware will bolt to. I have included a link to the installation instructions for you. On a vehicle that has seen at least one winter or is older, you will probably have grime and corrosion build up inside the weldnuts. I have included some links that will explain how to clean them out for hitch installation. If you plan...
