2006 Buick Lucerne - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • Trailer Hitch Wiring
  • 4 Flat
  • No Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Buick Lucerne with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


  • 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


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.

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 56047

Average Customer Rating:  4.9 out of 5 stars   (28 Customer Reviews)

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.


I would give it 10 stars.

I am extremely
satisfied. It was easy to install, and everything was included with the shipment. It shipped extremely fast. This is a great company to work with.

I really like the lighting. As we do not plan to use this hitch with lighting very often, most likely real often with our bike carrier, this was a perfect fit for us.

Seems to be very well constructed. And made of high quality steel.

You can’t miss with this one.

2015 Ford Fiesta

The wiring harness went so easy, for me no tools were needed. For me your site had the least expensive on the internet. Worked flawlessly. Thank you so much.


The harness arrived quickly, the instructions were easy to follow and it took about ten minutes to install. Very happy with this harness.

2015 Ford Fiesta

The product was as advertised and fit my car exactly. The order arrived in good shape and shipping was quick.
I will buy from etrailer again.


This harness was designed just for this application and fit right pin. PLUG n PLAY.

2011 BuickLucerne

The wiring hook-up was terrific. No more cutting and taping. Things snapped together easy and no guess work as to what wire had to be cut and spliced. I will never go back to the old way.

2014 Ford Fiesta

Gone are the days of cutting and splicing, this went on exactly as expected, using the factory connections. I could not be more satisfied.


The harness fit perfectly and it works great.

2014 Ford Fiesta

The wiring kit was perfect for my car and easy to install.


Part was as described. Easy installation. Only problem I had was the delivery. A week shipping from MO to WI. Not worth the lower price.

2009 BuickLucerne

Very good product. Fast and easy installation.

2016 Ford Fiesta

  • Do You Have To Disconnect the Battery to Flat Tow a 2015 Ford Fiesta?
    To Flat Tow your 2015 Ford Fiesta, you will need to disconnect the battery and your key will remain in your vehicle while in the off position. Complete instructions are found in your owners manual on page 152 under Recreational Towing. "Note: There must be battery power to properly move the transmission’s internal components to neutral in step 3. Also, moving the gearshift to the neutral position without first turning the ignition to the on II position limits the towing capability to...

  • Trailer Wiring Recommendation for a 2014 Ford Fiesta Hatchback
    Since the 2014 Ford Fiesta Hatchback has a different taillight setup than the Sedan model you would need to order a wiring harness with a converter built into it like the part # C56191 that you referenced. The # 56047 that you referenced would not be the correct kit for you.

  • Lighting to Tow a 2015 Ford Fiesta ST Behind a Motor Home
    Trailer wiring harness # 56047 is for a 2015 Ford Fiesta sedan. But the ST is a hatchback so the harness will not fit. For a hatchback you would use # 118641. Another issue is that you would not use this type of harness to tow the Fiesta behind the motor home. This harness is for a Fiesta to tow a trailer behind it. It does not work in reverse so you need a different lighting solution. Since there aren't any plug in tow bar wiring harnesses for the 2015 Ford Fiesta ST at this time, your...

  • Trailer Hitch Recommendations for a 2008 Buick Lucerne Base Model, Special Edition, or Super
    In order to determine if your 2008 Buick Lucerne is a standard model CXL or a special edition, there are a couple of things you can do. If the driver seat is a power memory seat that remembers your settings and your tires are size 245/50R18, then you have a special edition. But the definitive way to determine the trim level of your Lucerne is to contact a local dealer and have them run the VIN number of the car and they will be able to tell you for sure which one you have.

  • Hitch Recommendation for a 2015 Ford Fiesta
    Yes, we do carry hitches that are confirmed to fit your 2015 Ford Fiesta. If you have hatchback (excluding ST) then you would want the Curt Hitch part # C11067. If you have a sedan you would want the Curt Hitch part # C11369. For a ball mount you would want the part # C45521, pin and clip part # F-4, 2 inch ball # A-82, 1-7/8 inch ball # A-82. If you have a sedan you would want the part # 56047 for trailer wiring. We don't have a fit yet for the hatch models yet.

  • Can a 2006 Buick Lucerne Tow an 800 Pound Trailer without a Transmission Cooler
    According to the owner's manual for the 2006 Buick Lucerne it has a gross trailer weight capacity of 1,000 pounds maximum. It does not say that a transmission cooler is required. However, a transmission cooler is always a good idea, especially when towing, to keep the fluid cooler so the transmission is less likely to get damaged or wear out any faster than normal. If you do decide to install a cooler the most popular option for models with the 4.6 liter V8 is # D13503. And we also recommend...

  • Parts Needed to Convert Trailer to Electric Drum Brake Operation
    It is possible to have brake flanges welded to an axle that does not have them, but this requires specialized jigs that ensure perfectly correct alignment. Any errors in the orientation of the brake flange can cause all sorts of issues with brake performance and brake wear. This is not a typical DIY kind of project. Often when converting a no-brakes trailer to electric drum brakes it is far easier and often also more cost effective to simply replace the axle with one that includes brake...

  • Parts Needed To Flat Tow a 2015 Ford Fiesta Behind a Motor Home
    A plug in tow bar lighting system is not available for your 2015 Ford Fiesta but there are other options that will work. You could use a magnetic light kit, # RM-2120, a bulb and socket kit, # RM-155, or a diode kit, # 154-792-118158. The magnetic light kit will be the most cost effective option and the least permanent. The diode kit is the most involved of the installations and requires splicing into the vehicle wiring for installation. The bulb and socket kit bypasses the vehicle wiring...

    I do have a hitch option for your 2008 Buick Lucerne to transport a 500lb electric wheelchair, but it will require a trailer as your vehicle is not rated for the amount tongue weight that a carrier would have. What you'll need is the following parts: Hitch # C12044 Ball Mount # C45520 Hitch Ball # C40001 Hitch Pin and Clip # F-4 Wiring Harness # 56047 and a small trailer like the Detail K2 # K2MMT4X6 To be able to use an actual carrier like # FHG69ZR you'd need to have a full size SUV...
