  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • No 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.


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
  • Comes with dust cap for 4-way flat connector
  • 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.

nobody get a perfect score, always something to improve on. I am very HAPPY with each purchase from etrailer. Each new vehicle or past 10 yrs have had e-trailer hitches & wiring. Everything worked perfectly, delivery was on time as usual. Thank you again for an easy install on the Mustang.




by:
1994 Ford Crown Victoria

Works great! Meets/exceeds expectations. I really like how the receiver end comes with a cap to keep dirt and water from getting in and the long cord allows for convenient connection even with long tongue trailers. When not in use I tuck it into the trunk and truck lid closes fine without damaging cord, I have bought from them before I will definitely buy from them again, as a matter of fact I just purchased another similar connector for my Mazda truck. Thanks etrailer!

great item, made the wiring job extremely easy and with a great price...Thanks very much!

Product received.
Product installed.
Installation
easy.
Ground wire was not as I expected.
Ground wire was looped , connected to itself and sealed with a protective
rubber heat shrink.
There was no instructions related to this connection.
This ground wire pig-tail should be explained.


Comments
According to Curt, the # C55326 trailer wiring harness does not feature a separate ground wire that needs to connect to the vehicle chassis because the vehicles tail light wiring harness already grounds to the vehicle. An additional connection wasnt necessary.

Everything went great except for one thing....connectors are wrong ..no plug and play.


Comments
I have confirmed with my contacts at Curt and this wiring harness is confirmed as a fit for your Grand Marquis. The connectors from this wiring harness are located in the rear of the trunk behind the taillights. You may need to remove some of the interior lining of the trunk to be able to get to the connectors. There is a helpful image on page 2 of the instructions provided by Curt.

C55326
I investigated this product.

I took a gamble and ordered it, unfortunately the plug ins were different. So I went ahead and and cut the plugs off and hard wired into the vehicle harness. Not a big deal, was just hoping for a plug and play.




by:
1996 Mercury Grand Marquis

Received it the second day after I ordered it. Went on my 1996 Grand Marquis this morning. Every thing went well--tried to duplicate your helpful video. Did the installation myself with the car's rear end up about 2'. Used 2 milk crates on either side of hitch center so I could get hitch in place to mark my bolt holes on the frame. Expect it to work well for pulling a 4'x8' bed trailer




by:

I ordered a trailer wiring harness from etrailer. It took me all of ten minutes to install it. The easiest installation ever!




by:

when this wire harness came in I installed it within 30 mins very easy to do the directions that come with it were very clear easy to follow highly recommend this item




by:

Received product ahead of scheduled delivery date. Took only a few minutes to install and worked perfectly when plugged into my trailer.

THROUGH NO FAULT OF THEIRS I RECEIVED
THE WRONG PART NUMBER. I'm SURE I SAW THE CHEAPER PRICE AND CLICKED ON IT. UPON RECEIPT OF THE PACKAGE I IMMEDIATELY CALLED CRYSTAL AND INFORMED HER OF THE SITUATION. SHE INFORMED ME THAT SHE WOULD SEND THE CORRECT PACKAGE IMMEDIATELY. THE COMPASSION SHE SHOWED WAS EXCELLENT. I HAVE ORDERED ITEMS FROM THIS COMPANY BEFORE AND HAVE ALWAYS HAD EXCELLENT SERVICE. THANKS AGAIN CRYSTAL. WILL BE BACK AGAIN SOME DAY.




by:

Good quality materials used in this product. Easy to install, with no problems.

  • Trailer Wiring that Fits 1995 Lincoln Town Car
    For your 1995 Lincoln Town Car we have trailer wiring harnesses that are a confirmed fit like the Curt # C59496 which are universal style harnesses that require some splicing, but the kit you mentioned does not fit.

  • Trailer Wiring Harness for a 2003 Ford Crown Victoria
    For your 2003 Ford Crown Victoria you can use Hopkins trailer wiring harness # 46255. There isn't a T-connector that just plugs into the tail light wiring available for your vehicle so you will need to use this hardwire harness. You will also need a circuit tester such as # 40376 to test the vehicle tail light wiring. On the harness yellow is left turn signal, green is right turn signal, red is brake lights, brown is running lights, and white is ground. The other red wire with the butt...

  • Trailer Wiring Recommendation for 1993 Ford Crown Victoria and 1999 Mercury Grand Marquis
    For trailer wiring for your 1993 Ford Crown Victoria the part # C55326 is a confirmed fit. For your 1999 Mercury Grand Marquis you would need the part # 119190KIT instead. I attached an install video that shows the harness being installed.

  • 4-Pole Trailer Wiring Harness for 2007 Mercury Grand Marquis
    Curt trailer wiring harness kit # C55326 fits other Ford/Mercury vehicles but we do have options for a 4-pole harness for your 2007 Mercury Grand Marquis. Both hardwired-type harness kits for your Grand Marquis are shown on the linked page. I suggest the Tekonsha kit because it includes a circuit tester to help you find the correct vehicle wires for connecting the harness, and because we have found Tekonsha wiring products to be more reliable than most others. The harness I recommend is...

  • What Additional Steps Are Required For Installation Of The Curt Receiver # 13707 on Dual Exhaust?
    The Curt Trailer Hitch Receiver # 13707 only requires modification to the passenger side exhaust bracket on 2003 and later models with dual exhaust. You will not have to modify the exhaust on your 1997 Mercury Grand Marquis. If you had a 2003 or later model the passenger side exhaust hanger is removed before installing the receiver. Then it is reversed and attached with the additional 5/16" hardware included in the kit after the receiver has been installed. I do recommend installing...

  • Trailer Wiring Harness for a 2013 Ford Escape without Factory Tow Package
    For your 2013 Ford Escape without factory tow package the least costly trailer wiring harness is # HM11140514. But if it were me I would spend a few more cents and go with the Tekonsha harness # 118566 because we hear about fewer issues with the Tekonsha brand. I have linked videos showing example installations of both harnesses for you.

  • Testing Tail Light Wires on a 2001 Ford Crown Victoria to Install a Trailer Wiring Harness
    When installing a hardwire trailer wiring harness such as # 119190KIT you have to test the vehicle tail light wires to determine their functions using either the tester that comes with the kit or, if you just got # 119179, a different circuit tester such as # 40376. Testing the wires is required because there is no standard wire color and function code. Your 2001 Ford Crown Vic has separate turn signal wires from the brake light wires. The yellow wire on the harness goes to the left turn...

  • Which Curt 4 Flat Trailer Wiring Harness Fits a 2017 Ford Explorer
    The Curt # C55326 wiring harness is actually designed to fit certain model years of the Crown Victoria, Ford Mustant and Mercury Grand Marquis so I do not suggest it for your 2017 Explorer. However, the Curt # C56172 is a plug and play option for your Explorer. I included an install video we did with this on a 17 Explorer for you to take a look at as well. If you were looking for a hitch as well, the Draw-Tite # 76034 will bolt directly to your Explorer without the need for any drilling....

  • Trailer Wiring Harness Recommendation for 2011 Ford Crown Victoria
    For your 2011 Ford Crown Victoria we have universal trailer wiring harnesses that are a fit, but not the part # C55326 that you mentioned. The best solution is the Tekonsha part # 119147KIT which installs without requiring any splicing into the vehicle wiring. Or for a lower cost option that would be a bit more involved to install we have the part # 119179KIT.

  • 4-Pole Trailer Wiring Harness for 2005 Honda Element
    We do offer options in a 4-pole trailer wiring harness kit for your 2005 Honda Element, shown on the linked page, but all of these products are universal-fit hardwire kits. No plug-and-play option is available. Of the available products I recommend the Tekonsha kit # 119147KIT for its reliability and high-current tail light output of over 7-amps. Review and installation videos are linked along with an article that will aid your installation. If you ever need to upgrade the 4-pole to a...

  • Parts Needed For Adding a Trailer Hitch Receiver, Wiring and Brake Controller On a 2008 Lincoln MKX
    The Curt Trailer Hitch Receiver # C13067 is confirmed to fit your 2008 Lincoln MKX. This class III receiver is rated for up to 400lbs of tongue weight and a trailer up to 4,000lbs. Be sure to verify your maximum trailer capabilities with your Lincoln dealer and do not exceed the lower of the limits. You will need the Curt T-Connector Vehicle Wiring Harness # C56329 for your MKX, as the # C55326 you found fits older Ford cars and not your MKX. The Harness # C56329 will give you a 4-way...
