Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear, passenger's-side wheel well trim panel.


Torx Screw Locations

You will have to locate and remove the (5) T-20 Torx screws with a T-20 Torx bit (not included) and pull back on the wheel well trim panel. It might be easier to access this connection if you remove the additional Torx screw holding the harness in place.


Wiring Harness Location

Once you've located the wiring harness, remove the protective cover and plug in the connector.


Fuse and Relay Locations

Once you've plugged in the connector, insert the included fuses and relays into their locations in the fuse box, which is located in the engine compartment.


Once installation is complete, the 4-way flat 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 plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

I like how everything is included for turning a vehicle that didn't have factory tow package into one that does. The most difficult thing was taking the 6 torx head screws out of the fender well to access the tow plug. Other than that it was super easy. Highly recommend. 875519

  • How To Install a 4-Way Trailer Connector on a 2016 Buick Enclave
    If you have a 2016 Buick Enclave then there should be a tow plug that will allow you to connect a 4-way trailer connector without having to tie in behind the taillights or splice into any wires. This plug should be present whether or not you have the factory tow package however, if you don't have the factory tow package then you will need to install the fuses and relays that come with the kit. I recommend the Curt T-Connector Vehicle Wiring Harness part # C56245. If you take a look at...

  • Trailer Hitch and Trailer Wiring Harness Recommendation for 2015 GMC Acadia Without tow Package
    The Tow Ready # 118270 will work on your Acadia even if you don't have the tow package. The wiring harness includes the fuses and relays needed to activate the tow package wiring. I've confirmed this with Tow Ready. If you needed a 7-way connector, use # 118271. For a hitch, I'd recommend the Draw-Tite Class III trailer hitch, part # 75528. I've linked you to some installation videos. I hope you'll find them helpful.

  • Trailer Wiring Harness Kit Options for 2011 Chevrolet Traverse
    Curt 4-Pole trailer wiring harness kit # C56245 fits the Chevrolet Traverse for model years 2013 through 2017. For your 2011 Traverse we do offer similar plug-and-play wiring kits and the correct one will depend on how the car is equipped. If you have the factory tow package the car will have a round U.S. Car connector under the rear bumper that will accept a 4-pole plug-in harness # 118384 or a combination 7-way/4-pole harness like # HM40975. If the car does NOT have the factory...

  • Will Curt T-Connector Wiring Harness # C56245 Work with Hopkins Fold-Over Mounting Bracket
    I went out to the warehouse so I could physically test the fit of the 4-Way on the Curt T-Connector Wiring Harness # C56245 and the Hopkins Fold-Over Mounting Bracket # HM48595. I found that the 4-Way connector, along with the dust cap, were just a bit too large to allow the folding bracket to securely close around the unit. This particular bracket will not be the best mounting option for this harness. I instead recommend looking at the Tow Ready Mounting Bracket # 18144. You can use...

  • Does Factory Rear Air Conditioning on a 2017 Chevy Traverse Affect Trailer Wiring Harness # C56245
    Having factory rear air conditioning on your 2017 Chevy Traverse would not affect the fit or function of Curt wiring harness # C56245. It does, however, affect # C56181 or any other harness that plugs in line with the vehicle tail light wiring. From what I understand the AC components are in the way making it difficult to install a harness that plugs in line with the tail light wiring. But if you managed to gain access it will work. So something else is happening. When you say that the...

    By law your trailer has to have functioning lights. It would not be a problem if you were moving the boat and trailer around on your own property but out on the road you have to have lights. To add a 4-Way trailer connector to your 2015 GMC Acadia you can use # 119250KIT.

    You will actually install just two relays with the 4-flat wiring harnesses that fit your 2017 Chevy Traverse without the factory trailer connector. The Curt simply has an extra, but both will have two relays installed, at the same position on your Traverse, R15 and R16, as you can see by the cut out of the linked installation instructions I added for each: - Tekonsha T-One Vehicle Wiring Harness # 118270 - Curt T-Connector Vehicle Wiring Harness # C56245 I have added links to video...

  • Trailer Brake Controller Recommendation for 2014 GMC Acadia SLT with Factory 7-Way Tow Package
    Among the most popular and reliable trailer brake controllers we offer is the Tekonsha Prodigy P3, part # 90195. This proportional controller works with both electric and electric-over-hydraulic brakes and will ensure your trailer will stop in proportion to the tow vehicle, which saves wear and tear on the brakes of both vehicle and trailer. If your Acadia has a factory tow package with 7-way trailer socket at the rear bumper you'll need to order just the controller itself and the matching...

  • Height Above Ground of Draw-Tite Max-Frame Trailer Hitch # 75528 on 2013 Buick Enclave
    I have linked a video showing installation of Draw-Tite Max-Frame Trailer Hitch # 75528 on a 2010 Enclave; at the 3:30 mark there is a display of the receiver tube's height above ground when installed. On this vehicle the top of the receiver tube will be approximately 17-3/4-inches above ground. The exact height will depend on the tire's tread depth and the cargo and passenger load in the vehicle. If you need a 4-pole trailer wiring harness you can use # C56245 from Curt.

  • Brake Controller Recommendation and Install for a 2013 GMC Acadia
    You will need to start with a 4-way (if you do not have one). For that you would want the # C56245. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling...

  • Trailer Hitch and Wiring Recommendation for a 2014 GMC Acadia
    First let's start with a hitch for your 2014 GMC Acadia. For that you will want the Draw-Tite part # 75528. There are no hitch options for your vehicle that will allow it to keep the rear fascia, but realistically that shouldn't be a problem since it's main purpose is only for appearance purposes. I attached an install video for you to check out as well. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with...

  • Can Door In Fascia of 2013 Buick Enclave Be Replaced After Trailer Hitch is Installed

If you plan on towing a trailer, you'll need a few other items to complete your towing system: Trailer wiring harness, part # C56245 Ball mount, part # 2923 1-7/8 inch trailer ball, part # 19260 or for a 2 inch ball, use...
