CURT Custom Fit Vehicle Wiring - C55530

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered 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 behind tail lights
    • 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: 6 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 tail lights. You will have to remove the tail light assemblies and interior trim panels to access this harness.


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.

Product is very good and fit well Paper instructions for a little confusing video help quite a bit

Working great. not bad installing it either. I would recommend this product rather than try to wire it any other way.



by:
2005 Chrysler Pacifica

The product installed easily, and exactly like the instructions said. The only complaint I have is with the design. So you run the pigtail out the back hatch of the Pacifica. Which is okay, but it seems like with a bit more wire you'd be able to route it down through the tail light assembly on the drivers side and then along the hitch itself.

I'm afraid the door closing on it over and over again is going to sever the wires.

Hardest part was taking out the torks bolt for the belt re-tractor on the driver side.

  • How To Choose the Correct T-One Vehicle Wiring Harness for a 2007 Chrysler Pacifica
    In regards to a 2007 Chrysler Pacifica, the T-One Vehicle Wiring Harness part # 118381 is a fit for models with the factory tow package and the Curt Vehicle Wiring Harness part # C55530 for models without the factory tow package. If you had the factory tow package then you would have a 7-way trailer connector clearly installed on the exterior of the vehicle. I would be willing to bet you do not have the factory tow package so the # C55530 is likely what you need. Furthermore, this option...

  • Trailer Wiring Harness Recommendation for a 2005 Chrysler Pacifica
    For trailer wiring for your 2005 Chrysler Pacifica you would want the Curt harness part # C55530. This will plug in line with the taillight harnesses of your vehicle. I attached an install video for you to check out as well. For a mounting bracket you would want the part # 18144.

  • Installing 7 Way Connector 32145 on a 2005 Chrysler Pacifica
    If you have the factory tow package, installation of part # 42145 is very easy. There will be a connector on a wiring harness that will fit this part, it will be tucked up, maybe taped, somewhere close to the rear bumper. You will then attach the mounting bracket in a convenient location near the hitch, and it will hold the 7 way plug. If you do not have the factory tow package, you will need the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55530. I've...

  • Recommended Trailer Hitch for 2006 Chrysler Pacifica
    I do have a solution for you, however the Curt Trailer Hitch Receiver # C13362 referenced in your question is not designed to fit your 2006 Chrysler Pacifica. I instead recommend looking at the Curt Trailer Hitch # 13529. This Class III hitch is confirmed to fit your vehicle and will provide a 2 inch receiver opening with a gross trailer weight capacity of 3,500 pounds. No drilling will be required for installation. Keep in mind that the exhaust and spare tire will need to be temporarily...

  • Trailer Wiring Connector # 118303 for 2005 Chrysler Pacifica Shows Constant Power on Running Lights
    There should not be any major constant power draw on any of the circuits on wiring harness # C55530. Though there may be some residual power coming through. There may be a short or ground issue that is causing some power to trickle through. Check the vehicle side connector for any dirt or corrosion and clean it out. Do the same for the connector on # CR-600LED.

  • 4-Pole Trailer Wiring Harness for 2004 Chrysler Pacifica
    We can help you with a trailer wiring harness for your 2004 Chrysler Pacifica that already has an aftermarket Curt hitch installed. For the Pacifica without the factory tow package you can use 4-pole wiring harness kit # C55530 from Curt. This kit provides you with basic trailer alighting functions: brake, turn and running lights. This is all you need for a trailer without brakes and that does not have an on-board battery. If you instead need a fully-functioning 7-way connector that provides...

  • Trailer Wiring Recommendations for a 2007 Chrysler Pacifica
    The Hopkins Endurance Quick-Install 7-Way Trailer Connector # HM42190 that you referenced plugs into the factory harness near the rear bumper if your 2007 Chrysler Pacifica was equipped with a factory 7-way. If you do not have any trailer wiring you would first need to start with a Curt Wiring Harness # C55530. This will provide you with a 4-way and is the style that plugs in line with the factory taillight wiring harness like you referenced. To convert the 4-way to a 7-way you will need...

  • Items Needed to Install Brake Controller on 2005 Chrysler Pacifica
    Because the 2005 Pacifica is not pre-wired for a brake controller, the controller would need to be hard wired using a Brake Controller Install Kit # ETBC7. There is not a wiring adapter available. Although the install kit contains everything needed to install the brake controller, the vehicle will need a functional 4-pole trailer connector, part # C55530 if it does not already have one. The adapter included in the kit will convert the 4-pole to a 7-way trailer connector. Once the adapter...

  • Parts Needed to Install a 7-way on a 2007 Chrysler Pacifica
    If you do not have a 4-way yet you will first need one. In order to install one you will need the Curt Wiring Harness part # C55530. Now if you only need to go to a 7-way for taillight purposes all you would need is a Adapter 4 Pole to 7 Pole # 37185. You would just need to plug in your 4-way to the 4-way of the # 37185 and the adapter would control the taillights of your trailer. If you need to activate trailer brakes instead of the # 37185 you would need the part # ETBC7. This comes...

  • Replacement 4-way Connector for 2007 Chrysler Pacifica w/ Bad Converter Box
    Unfortunately the converter of the Curt # C55530 you have installed on your 2007 Chrysler Pacifica is not a replaceable part and the entire wire harness and would need to be replaced. This is unfortunately pretty common with 4-pole wire harnesses, which is why there's only a 1-year limited warranty.

  • 4-Way Flat Wiring Harness Fit for 2006 Chrysler Pacifica
    To add a trailer wiring harness to your 2006 Chrysler Pacifica, you will want to use a wiring harness with a converter. The converter works to change the separate taillight wiring on your Pacifica to combined wiring that is used on trailers. To be able to connect your Pacifica to your Jayco trailer that has a 4-Way flat connector, if your Pacifica did not come with a factory 7-Way connector, I recommend the # C55530. This is a custom fit wiring harness that will install behind the taillights...

  • 2005 Chrysler Pacifica Wiring Harness Warranty
    I am sorry you are having a problem with your wiring harness, unfortunately there is only a one year limited warranty on the T-One Wiring Harness. There is no subset of this product and 118303 is the only harness available for the 2005 Chrysler Pacifica. You may want to purchase the vehicle specific wire harness like the Curt # C55530 so that you do not risk overloading a circuit or causing a fire.

  • Will Full Size Spare Still Fit Under 2005 Chrysler Pacifica After Installing Curt Trailer Hitch
    After installing the Curt Class III Trailer Hitch Receiver # 13529 your full size spare tire will still fit in the spare tire carrier under your 2005 Chrysler Pacifica. The spare tire is lowered or removed for installation in order to make it easier to access the frame and install the trailer hitch. Once the hitch is installed, the spare tire can be raised back into position. I have attached an installation video of this trailer hitch being installed on a similar Pacifica to yours as...

  • Will Spare Tire Fit Under 2008 Chrysler Pacifica With Trailer Hitch Installed
    Yes, the spare tire underneath your 2008 Chrysler Pacifica will fit back under the car when you install Curt Trailer Hitch Receiver # 13529. If you take a look at the cut out of the linked installation instructions you can see where it specifies raising the spare tire back into position; it only needs to be lowered to install the hitch. For wiring which will give you a 4-way connector and allow you to power your trailer's lights you need Wiring Harness # C55530. I also recommend checking...

  • Fuse Location for Trailer Wiring Harness # C55530 on 2004 Chrysler Pacifica
    When installing the Tow Ready Curt Wiring Harness # C55530, on your 2004 Chrysler Pacifica, you will need to access the fuse box under the hood on the driver side near the front of the vehicle.

  • Trailer Hitch, Ball Mount, Ball, and Trailer Wiring Recommendations for a 2004 Chrysler Pacifica
    In order to pull a trailer with your 2004 Chrysler Pacifica, you will need a trailer hitch, a ball mount, ball, pin and clip, and trailer wiring. For a trailer hitch, you can use the Draw-Tite hitch, # 75522, that you have referenced. I have included a link to the installation instructions and a link to a video showing a typical installation for you. For a ball mount, ball, and pin and clip, I recommend the etrailer ball mount kit, # 989900. This kit comes with 2 ball mounts, a 2 inch...

For Pacfica models that did not come with a factory 7-Way connector you will instead need to use wiring harness # C55530. I have linked a video showing an example installation for you.

In the video, our installer actually uses one of the bolt holes used by the bracket to install the hitch.

  • Troubleshooting Trailer Wiring Harness on 2006 Chrysler Pacifica Not Receiving Power
    The first thing I'd recommend doing is making sure BOTH fuses are installed, the 10A installed inline in the power feed for the converter and the 20A fuse is installed in position 10 in the fuse box, listed as 'Trailer Tow'. If the fuses are installed and not blown, and the T connections that install inline between the taillight assemblies and the vehicle's taillight wiring harnesses are secure. If that all checks out, use a circuit tester like # PTW2993 and check the circuits on the...

  • Adapter Needed To Convert A 7-Way To 5-Way And Lockout Surge Brakes
    If you have a factory 7-way on your vehicles they should be wired to the reverse light circuit so all you would need is an adapter to go from your 7-way to a 5-way like part # 707250. Typically this wire is purple or yellow and is the center pin of the 7-way. You can put your tow vehicle in reverse and use a tester like # PTW2993 to see if the 7-way is indeed wired to the reverse light circuit or just use the adapter to test if it is. If it's not then you'll need to run a wire from the...

  • Is There a Difference Between the Hitch Receivers Offered for the 2007 Chrysler Pacifica 4.0
    The two hitch receivers offered for the 2007 Chrysler Pacifica, Curt # 13529 and Draw-Tite # 75522, are basically identical, have the same towing capacities, and will install in the same way. There really is no way to get around lowering the exhaust and removing your spare tire to ease the installation process so it is highly recommended. Some say that Curt hitches have a better powder coating but for the most part, price is going to be the main difference. Now mattresses on the other...

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2007 Chrysler Pacifica
    To add a 7-Way trailer connector and brake controller to your 2007 Chrysler Pacifica you will start by installing a 4-Way harness # C55530. Then to add the 7-Way and the wiring for the brake controller you will need # ETBC7. I have included some links that show and explain the ETBC7 installation for you. There isn't a brake controller harness specifically for your Pacifica so the controller, # HM47294, will need to be hardwired in. The ETBC7 comes with the parts needed to do this.

    According to my research, your vehicle has a towing capacity of 2600 lbs. This means that the trailer you choose plus what's loaded on it should not exceed 2600 lbs. For a trailer hitch, I'd recommend the Curt Class III, part # 13529. You'll also need a trailer wiring harness, part # C55530. You'll also need a ball mount and the appropriately sized trailer ball and a hitch pin and retaining clip. When installed (assuming that your Pacifica has stock tires and ride height), the hitch I...
