CURT Custom Fit Vehicle Wiring - C55372

  • 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. 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 point in rear cargo area
    • Plug in 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 either behind the driver's-side access panel in your rear cargo area or beneath the floor of your 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 plug 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.

All good worked as it should.

I was trying to order tailer wiring for a 1983 Camaro what I got/ordered was for a Chevy tracker, or three Suzuki models. The one pictured on your website showed a wiring diagram printed on the product case which does not exist on the unit delivered.

Oh boy, you are right. This harness will not fit your 1983 Camaro. Part # 18252 will fit though! You can get a return and new order set up with our customer service team! Ill send your info over to them!

Snapped right on wasn't sure what to do with what I guessed was the ground wire...
Called the help line... on hold for 2.5 Beetle's songs... and they confirmed my guess and suggested ways to secure it to frame



by:

Very easy to install and it is a very well made product.



by:

Easy and accurate ordering process, with fast shipping. None of the pictures or details fit where the wiring harness connection location was on my 03 Tracker. My harness connection was taped down about 2' toward the front from the Jack storage compartment. Snap-out removal of the top of the side panel from rear to back seat was required. Once you removed the tape holding the harness connection it would barely reach the Jack storage compartment.

Works fine, install more difficult for my model, I guess.



by:
2001 Chevrolet Tracker

Once I found the vehicle wiring, just plugged in and everything worked.
The connector is behind the side panel in the luggage compartment so you have to partially remove the side panel to expose the plug.

I bought this trailer from HD it was all wired but not my Suzuki Grand Vitara , I looked all over town for a wiring harness , nothing then looked on the internet , found etrailer.com looked like the best one for my car and the price was right , so I ordered it and it turned out to be the best choice , it worked perfect and easy to hook up , hard to believe how good everything worked out . Thanks , Ray



by:
2003 Chevrolet Tracker

My wiring harness plug was "hidden" behind the driver's side rear wheel panel. I had to pull the panel out from the top and finesse the tape off and the plug free and back. I didn't secure the "black box", just stuffed it in the jack compartment. The connection pigtail passes out under the taillight and under the body perfectly to the hitch.

I used this factory plug in pigtail to replace a "splice job" on the tail lights. Reasonably quick, simple, easy no fuss, and it works.



by:

Easy way to hook up trailer wiring. I removed tail light to route wire under and along frame. Had cut notch in bottom of gasket and plastic bottom of tail light housing. Sealed with dab of silicone.



by:

took 5 min. to put on car



by:

it was super easy to install and I use it all the time. I even got it to power my backup cam.

2002 Chevrolet Tracker

Only took a couple days to get this hitch and wiring harness mailed to my house, very happy with that



by:

Easy to install. Five minutes max. Most of that time taking jack out and putting it back. Unit just plugs in to connector and your done. Thanks



by:

The install was simple and easy. It only took 5 minutes and I took my time. Just tap in the ground with the provided self tapper then hook up to the trailer and go.



by:

Great instructions helped to install this well constructed product easily.

easy straight forward installation, fit perfectly

  • Where to Find Connector for Installing Trailer Wiring on a 2001 Suzuki Vitara
    The Curt trailer wiring harness part # C55372 is a confirmed fit for your 2001 Suzuki Vitara. The connector you would be looking for is located on the inside of the driver side tire jack compartment. It is taped to the vehicle wiring harness just forward of the jack compartment. If you still don't see it try removing the taillight assembly to gain further access. That is something a customer had to do with their similar Vitara.

    For towing a 3,500 lbs you would want to at least get a Class III hitch with a 3,500 lb capacity. You should note that just because the hitch is rated for 3,500 lbs that does not necessarily mean you can tow that amount. You will also need to consult the owners manual of your vehicle to check to see what towing capacities they have listed and be sure not to exceed the lowest capacity of all of the components in your setup. From the research I did it looks like your vehicle has a 1,500 lb...

The easiest way to access the taillight wiring will be by removing the taillight assemblies from the vehicle.

  • Install of Curt Trailer Wiring Install Harness on 2001 Suzuki Vitara that Had Previous Wiring Kit
    The good news is that all you have to do is remove the quick splices you have on the taillight wiring and install the Curt trailer wiring connector part # C55372 like the instructions recommend and the kit will be installed properly. The quick splices are what is holding the old harness to the vehicle wiring but once you remove them and the wiring of the old harness the car will not be affected.
