  • 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.


  • 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 either behind tail lights or near rear bumper
    • 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 either behind the driver's-side and passenger's-side tail lights or beneath your car by the rear bumper.

Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.

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.

Super easy to install. No cutting wires. Just plug and play and everything works. Very good product.


Got hitch but u.p.s. did job on box. Hole in box where both frame braces went thru box. Parts bag broke only missing 1-3/16 bracket.


The wire harness works perfectly. Hooks right up. Only need to drill a small hole for a ground.

  • Does Trailer Wiring Harness for 2005 Chevy Malibu Maxx Need Diodes
    Since the Curt T-Connector Vehicle Wiring Harness # C56013 doesn't come with diodes you should be just fine without diodes when installing this on your 2005 Chevy Malibu Maxx as Curt tends to do a good job at determining the need for diodes. If you'd feel safer with a measure of protection between the vehicle and trailer wiring then I recommend checking out the Hopkins Plug-In Simple Vehicle Wiring Harness # HM11141605 instead. This tees in behind the tail lights like the Curt but it also...

  • Trailer Hitch Fit and Towing Capacity for 2009 Pontiac G6
    The Draw-Tite Class II hitch # 36426 is a confirmed fit for your 2009 Pontiac G6 and the hitch itself offers a maximum towing capacity of 3500-lbs. If your trailer has a 2K-rated axle then the hitch will have plenty of capacity to tow it, but you'll also want to check the G9 owner's manual since the car itself may have a different towing capacity than the hitch. The lower-rated item determines overall capacity. A hitch installation video is linked for you. Towing also requires a ball,...

  • Trailer Hitch, 2 inch Ball, Ball Mount and Trailer Wiring for 2007 Chevy Malibu
    Sounds like you are looking for a trailer hitch for your 2007 Chevy Impala and a ball mount that has a 2 inch ball on it. For that we have the Curt # C12272. Then for a ball mount you'd want the # C45147. For trailer wiring you'd also want the # C56013 and you'd be set.

  • Trailer Wiring and Tow Dolly Wiring for a 2009 Pontiac G6
    You will need to use a circuit tester, like # PTW2993, in order to determine the functions of the taillight wires on the 2009 Pontiac G6 if you are hardwiring a 4-Way connector to the vehicle. This involves turning on the blinkers, brake lights, and running lights in succession and then probing each wire to match the right function with the right wire. I have included a trailer wiring FAQ article that goes into more depth of wire and function below. I recommend installing the Curt Custom...

  • Will Draw-Tite Hitch # 36426 Fit 2009 Pontiac G6
    The Draw-Tite Trailer Hitch, part # 36426 you referenced, is a fit for your 2009 Pontiac G6, if it is not a convertible. This is a class ll hitch with a 1-1/4 inch receiver opening. The maximum towing capacity is 3500 lbs, and the maximum tongue weight is 300 lbs. I would recommend you check your owners manual or with your local dealership concerning the towing capacity of your vehicle if you are planning on towing. If so, you will need a ball mount. I would recommend Class II ball mount...

  • Troubleshooting Rear Turn Signals on 2004 Chevrolet Malibu Maxx
    I suggest you first check the rear turn signal bulbs in your light housings and then also the turn signal fuses in the power distribution box in your 2004 Chevrolet Malibu Maxx. Dealer wiring repairs can indeed be costly but checking/replacing bulbs and fuses is easy and inexpensive. If your bulbs and fuses are good then you'll want to inspect the wiring and connectors in the lights for any signs of loose wires or fasteners. Check the bulb sockets for signs of discoloration - even very...

  • Ball Mount and Wiring Recommendation for Draw Tite Hitch that Fits 2005 Pontiac G6
    The Draw Tite hitch part # 36426 that you referenced does not come with a ball mount but we do offer the recommended ball mount from Draw Tite as # 36065. This will give you a 5 inch rise. For hitch balls you'd want the part # 19258 for a 2 inch ball or part # 19256 for a 1-7/8 inch ball. If you are unsure what size ball you need check the coupler on your trailer as it will be listed there. You'll also need trailer wiring to activate the lights of the trailer you plan to tow. For that...

  • Can Curt Trailer Hitch # 12333 on a 2006 Pontiac G6 Tow a Jet Ski
    The Curt Trailer Hitch, # 12333, is a class II hitch rated for 350 pounds of tongue weight and 3,500 pounds of gross trailer weight. As long as your trailer and jet ski do not exceed that, and the 2006 Pontiac G6 has a high enough towing capacity, it will be strong enough for your application. You can find the towing capacities of the vehicle by looking in the owners manual. If the vehicle and hitch have different towing capacities, go by the lower rating of the two. I have included a...

  • Trailer Hitch and Wiring for a 2010 Pontiac G6
    Trailer hitch # 36426 is a fit for a 2010 Pontiac G6 but I do have a hitch that is a fit. Another option you can use is Curt hitch # C12333. I checked with Curt and it is listed as a fit for the 2010 G6. I have linked a video showing installation for you. If you plan on doing any towing please consult the owners manual first for the vehicle capacities. The correct ball mount is # C45520. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. For a trailer wiring harness...

  • Hitch and Accessories Recommended for 2006 Pontiac G6 GTP Copue
    There is no reason why you could not use a hitch on your G6 GTP. The Draw-Tite Class II Receiver Hitch, part # 36426 is a fit for either the coupe or the sedan. The hitch has a towing capacity of 3500 lbs, and a tongue weight capacity of 300 lbs.

  • Parts Recommendation for a 2005 Chevy Malibu Maxx to tow a 2,000 lb Boat and Trailer
    First thing you need to do is check the owner's manual of your 2005 Chevy Malibu Maxx under the towing section to see what Chevy lists as the towing capacities of your vehicle. The Curt Hitch part # C12280 that you referenced is confirmed to fit your vehicle and has towing capacities of 350 lbs tongue weight and 3,500 lbs total trailer weight. If your owner's manual lists a lower figure you will need to go with that as the capacity as a towing setup is only as strong as it's weakest component. For...

  • Installation of Curt Class II # C12280 Hitch on 2005 Chevy Malibu Maxx
    To install the Curt Class II # C12280 hitch on a 2005 Chevy Malibu Maxx, you would need to drill two holes, one in the underside of each frame rail, as outlined in the instructions I've linked you to. If you'll be doing some light duty towing with your hitch, you might also need the following: Trailer wiring harness, part # C56013 Ball mount, part # C45520 1-7/8 hitch ball, part # C40001 2 inch hitch ball, part # C40018 Locking hitch pin, part # e98882

  • Parts Needed for Towing Trailer With 2005 Chevy Malibu Maxx
    You can tow a small trailer with your 2005 Chevy Malibu Maxx, and you can definitely use the 2" Hitch Ball # C40018 which has a 3,500 lb weight capacity. That said, you need to get the correct size hitch ball that fits your trailer's coupler and small trailers often use a 1-7/8" hitch ball and for that you will need the 1-7/8" Hitch Ball # C40001 which has a 2,000 lb capacity. Either amount is actually going to be more than enough for you to tow with your Malibu because I took a look at...
