    • 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 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.

Wiring harness arrived quickly and was easy to install. Would gladly order again from etrailer.

Plug and play! Very simple, easy installation. No cutting or splicing required. Took about 10 minutes. High quality materials. Very happy with my purchase.

A install video would have been a little easier. Fit was perfect!

It was the easiest way to wire for a trailer. No soldering cutting etc. It was perfect. Unplug the car's wiring harness and plug in the T-connector adapting harness. So easy. When I sell the car and get another Matrix I will be able to unplug it and use it again if it fits another year.

I would recommend this to anyone.

The Curt C55522 trailer wiring harness you purchased is a fit for the 2000-2002 Toyota Echo and the 2003-2008 Toyota Matrix, as long as your next vehicle is among those models and of those model years, the wiring harness would work fine on the next vehicle.



by:

Nice quality connectors. Super easy to install. Well designed kit.



by:

Continues to work as intended after a year. It looks much cleaner and is much more reliable than an universal module. In my case, all connections are kept inside the car when not in use so the 4 pin connector doesn't rot like they often do in the winter here in Canada. the only thing that didn't hold is the double face tape to stick the module somewhere.

Great and easy. Looked at the sheet enclosed in packing.... Well packed...box in a box....another similar instructions inside product packing... Too easy, unsnap the lighting connector on each side, make sure to follow convention for druveraide, plug in harness...plug orig connector into harness....too easy.


Thanks.

This Wiring Harness was used to replace another brand that had failed, and it only took 15 minutes to install it . It is a very clean and almost invisible Wiring Harness.
Thanks to etrailer for the quick shipping .



by:

Plug and play into the existing wiring harness, the only other thing you have to do is sand away the paint and use a screw for the ground wire.



by:

The wiring harness is easy to install, but it has a ground wire that the instructions don't mention at all that you have to connect to whatever ground you can find. I'll probably wind up extending the wire and running it to one of the cargo-latch holding bolts, it seems to be the best ground in the tail-light area that is easy to get to.



by:

Works as expected - very sturdy! What more can I say? It does the job!

  • Recommended Trailer Hitch And Small Trailer For A 2003 Toyota Matrix XR Hauling A Motorcycle
    I went ahead and checked out what we have for your 2003 Toyota Matrix and while we do not have any class III hitches that'll work with your vehicle, we do still have other options available. Instead, I recommend checking out the Curt Trailer Hitch Receiver # C12221. This is a class II trailer hitch that is a custom fit for your vehicle, has a maximum towing capacity of 2,500-lbs, and a maximum tongue weight capacity of 250-lbs. With that being said, a class II hitch is not going to be...

  • Why Do Some Trailer Wiring Harnesses Have Wire that Runs to Vehicle Battery
    Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others need to have the power drawn straight from the battery to protect the taillight circuits. So the connection has to be made to the vehicle battery otherwise the harness will not work. That said, if you have a 2005 Toyota Matrix like you...

  • Trailer Lights Stay on All the Time when Connected to 2006 Toyota Matrix
    This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. Converter # C55522 does have a separate white ground wire that needs to be attached...

  • Can Trailer Wiring Touch Heat Shield of Exhaust Near Rear of Vehicle
    Exhaust heat shields that are at the rear of a vehicles exhaust system would not get hot enough to melt wire or be an issue. Your 4-way wiring contacting the heat shield there would not be an issue.

  • Can Ultra-Fab Motorcycle Carrier UF48-979033 Hold Yamaha WR250R Dirt Bike on 2006 Toyota Matrix
    The 295-lb dry weight of your Yamaha WR250R dirt bike is well within the 500-lb maximum capacity of the Ultra-Fab Motorcycle Carrier UF48-979033. However, this 2-inch hitch size is not offered for your 2006 Toyota Matrix; only 1-1/4-inch Class I and Class II hitches are made for your car. The highest-rated hitch for your car is rated at 250-lbs tongue weight (TW) which is downward force on the hitch. Even without the 35-lb weight of the Rage carrier added in you would already be over the...

  • Parts Needed to Tow With 2006 Toyota Matrix XR & Can Bikes be Brought
    I'll just rip this band-aid off as fast as I can but there is just not a way to use a standard hitch-mounted bike rack and tow at the same time with your 2006 Toyota Matrix XR. The issue, like you said, is the 1-1/4 inch hitch not having an adapter; even if it did though, hitch adapters reduce hitch capacity by 50% so you'd be going over that as well. The only solution would be to add a roof rack and two roof-mounted bike racks, and that's awful expensive for one trip. If you want to do...

  • Best Wiring Harness For 2005 Toyota Matrix Towing Yakima Rack and Roll Trailer # Y08107
    Since the Yakima Rack and Roll Trailer, # Y08107, can draw a total of 8.7 amps with every light bulb turned on, the best option would be to install the Circuit Protected Vehicle Wiring Harness, # C59496, on your 2005 Toyota Matrix. This harness powers the trailer's lights directly from the tow vehicle's battery so the draw on your vehicle's taillight circuit is virtually eliminated. The maximum rating for this harness is 4.2 amps per circuit for stop/turn and 7.5 amps for taillights. Another...
