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.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56245 Review

Today we're going to review part number C56245. This is a Curt T-Connector Vehicle Wiring Harness with the 4-Way Flat Trailer Connector. This is a custom fit part number. It is designed to fit the Buick Enclave, Chevrolet Traverse and GMC Acadia, with or without the factory tow package starting with the year 2013 model. I would recommend to go to the product page for this part number on our website. At the bottom of the page it will list the exact years and models that this will fit on. This part includes everything shown here.

The wiring harness, set of nice instruction, 7 fuses, 3 relays and then a couple of zip ties. This will allow you to quickly and easily install this 4-Way trailer connector on your vehicle. This connector here will plug directly into your tow package port at the rear of your vehicle and it will provide a 4-Way flat trailer connector on the back of your vehicle to power your trailer signal lights. This is designed for use on vehicles with or without the factory tow package and this 4-Way is also compatible with the 5-pole, 6-pole or 7-pole adapters that we do sell separately. It does connect quickly and easily; there is not cutting or splicing of wires. Basically what you'll do is start on your passenger side and at the rear you'll go to the passenger side rear inner wheel well trim panel and you'll locate and remove five T20 Torx screws.

It does require a T20 Torx bit that's not included in this so you do need a T20 Torx bit to remove those screws. Once you get those screws removed you just pull back the inner wheel well trim, locate the vehicle's taillight wiring harness and then you'll see the vehicle's tow plug connector there. You'll just remove the protective cover from that tow plug connector and it should match up to this connector right here. You just plug in this connector and run your 4-Way to the back of the vehicle. To complete the installation you'll just go to the front of the vehicle in the engine compartment and in the fuse box you'll need to insert the three relays and then the seven fuses. There's three 30 amp fuses and four 10 amp fuses. Basically the instructions are very detailed and they'll actually even show you the pictures of where those fuses and relays go.

It's a very good set of instructions with this wiring harness. It also does come with a dust cap to cover the 4-Way. I already have it installed on the plug. You can just pop that dust cap off, plug in your connector, and then when you're done using it, to protect it just put the dust cap back on. Just a few specs on this wiring harness: the maximum amperage for this harness on the stop and turn lights would be 7 1/2 amps per circuit and on the taillights would also be 7 1/2 amps per circuit. That should do it for the review part number C56245, the Curt T-Connector Vehicle Wiring Harness with the 4-Way Flat Trailer Connector. .

GMC Acadia

The wiring harness fit my Acadia just the way it was supposed to. It attaches up in the rear fender well beside the wheel on the passenger side. Not an easy place to get to, so I took six screws out so I could pull the fender out to get enough room for my hand, so I could attach it. The harness was just long enough to reach the hitch. I ran it through the back bumper so it shouldn’t catch on anything. 662541

I was a little worried about the connector fitting but it’s a perfect fit. Just a hard spot to get into on the suv. You’ll need to install fuses to make the wiring harness work. The flat 4 plug fits well. 679547

  • 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.

  • 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.

    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.

  • 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...

    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.

  • 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...

  • 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
    Although it wasn't possible with 2012 and earlier models, the 2013 and later Buick Enclave models allow the rear fascia door to be replaced after the Draw-Tite Class III hitch, part # 75528 has been installed. You can see this in the video I've linked for you. 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...

Both hitches can be seen on the link provided; both share the same installation note that the fascia door panel must be removed for hitch installation and possibly cannot be reattached. We do not offer any hitch that avoids this potential requirement. You may be able to trim this panel satisfactorily in order to re-install it. Of the three hitches...

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.
