Great product, installation couldn't be easier. Kudos to eTrailer for putting together great install videos!

The entire wiring took me fifteen minutes. I went to my son in laws house, picked up his trailer that I am borrowing, and everything worked just well. I put the trailer hitch on a few days ago, and all though it took me longer to do than I anticipated (two hours instead of one) I was very pleased with your instructions. It took me longer than I anticipated because I had a very small clearance to get my socket and ratchet past the muffler....on both sides. And I dropped the muffler at the back end, but it only gave me an additional inch to work with. I made the mistake of tightening five of the bolts, and when I went to insert the sixth bolt it did not line up to the hole by a smidge amount. I then had to go back and loosen the other five half way out to give me movement, then get the sixth bolt started into the hole, and tighten all six of them. The slight clearance on the two above the muffler allowed me to use a wrench 1/8 turn at a time. But eventually I got the job done.

Thank you,
Dave Koenders

Super easy to install. I've never done wiring on a car before so I was a bit worried at first. But after watching the installation video provided from etrailer and going at it myself, it was a breeze and I laughed at how worried I was. To this day, I have never had an issue with it and it's been through a year of being used countless times.

Very smooth purchase

2010 Chevrolet Traverse

I had never installed a trailer wiring kit before, but it was a very easy install. It fit my 2010 Traverse perfectly. If I had a question it was addressed in the instructional video posted on the website. I looked at other wiring kits, but they were much more expensive, and you had to buy the 4 pole connector cover seperate (this one comes with one). All around very satisified.

I also bought the mounting bracket (18144), and the hole placement was an exact fit with my hidden hitch (no drilling required).



by:

Hitch is everything I could want. It was so easy to install took about 30 minutes like you stated on the web. Finish is extraordinary. fit perfect. The wiring harness was also easy to install and of excellent quality. I couldn't believe it got here so fast 2nd day from when ordered. I was able to fit my rear bumper door back on the car hiding the hitch completely from view. The video presentation was so helpful with the installation. Your CEO should be very proud of the well trained, organized and sincere staff representing e-trailer. I will certainly recommend your company to all I know.

Chevrolet Traverse

This was the easiest install ever. The hitch bolted directly to the hole pattern on my Chevy Traverse as advertised. The instructions on you tube were as easy to understand as the instructions they sent. The wiring harness is plug and play easy. Two hour install by myself. I recommend this product to everyone. The quality of this hitch is second to none. I am impressed!



by:

Easy to install. Wiring harness was easy also



by:

This product was exactly as described and fit my vehicle perfectly. I had to remove the tail lights during the installation but after that hooking it up was a breeze. The product has functioned flawlessly for over a year now.



by:

The wiring harness was very easy to install and works great.

Fit as specified to the vehicle. Easy to follow instructions and all needed hardware included. Performing great.

Hitch and electrical were quickly delivered in good shape. Installed in about an hour and looks to be of fine quality. All parts present and instructions your video made installation a sap.
Thanks.



by:

Excellent. Easy to install. However, learned to not disconnect the battery without some form of saver because started having issues with the car computer(s) shortly thereafter, i.e., blend doors, traction control, and break warnings. Happy with the product, just not the problems after installing.

  • Parts Needed To Install a 7-Way and Brake Controller On a 2010 Chevy Traverse Without Tow Package
    Yes, you can install a 4 and 7-way trailer connector on your 2010 Chevrolet Traverse along with a brake controller. In order to do this you will however need a few parts which I have listed for you below. Curt T-Connector Vehicle Wiring Harness part # C56027 7-Way RV Upgrade Kit for Trailer Brake Controller Installation part # ETBC7L Curt Echo Mobile Trailer Brake Controller part # C51180 The Curt T-Connector is plug and play so all you will have to do is remove the tail lights for a...

  • Which Curt Trailer Wiring Connector # C56027 Goes to Left and Right Side of 2010 Chevy Traverse
    For the trailer wiring harness part # C56027 the green wire goes to the passenger side rear taillight assembly and the connector with the yellow wire goes to the driver side. I also attached an install video for this for you to check out as well on a similar 2012 Chevy Traverse.

  • Hitch, Ball Mount and Wiring Harness Options for 2012 Buick Enclave Without Factory Tow Package
    For your 2012 Buick Enclave the Draw-Tite 2-inch Class III hitch # 75528 is a confirmed fit. Install instructions and a complete install video are linked for you. The hitch comes with all needed hardware. You will also need a ball mount, hitch ball and pin/clip. I suggest ball mount # 989892. In terms of the wiring harness options you ask a very good question. The available products, non-powered models # 118450 and # C56027 and the powered converter model # HM11141615, differ in one important...

  • Recommended 7-Way Wiring Harness for a 2011 Buick Enclave
    Yes, there is. You will need two separate wiring harness though since your 2011 Enclave does not have the towing package. The first one is the Curt Wiring Harness item # C56027. This harness is custom fit and plugs into existing wiring which is located either behind the driver's-side and passenger's-side tail lights or behind the rear bumper. The second harness you will need is the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes a pre-wired 7- and...

  • How Can I Connect a 7-Way Wiring Harness to My 2010 Chevrolet Traverse
    Yes you will need a T-Connector Wiring Harness with a 4 Pole Flat Trailer Connector # C56027 to connect to a 7-way. If you're planning to use a brake controller with your Traverse you will need the Universal Installation Kit for Trailer Brake Controller - 7-Way and 4-Way Flat # ETBC7. This will be all of the wiring you'll need for the brake controller. I've included an installation video of the wiring on a 2011 Traverse which will be very similar to yours. If you don't have a trailer...

  • Trailer Wiring Harness for 2012 Chevy Traverse Without Factory Wiring
    You'd have to go with a trailer wiring harness for your 2012 Chevy Traverse that does not use the factory wiring/connections and instead go with the # C56027 which installs by plugging inline with the taillight connectors.

  • Which Trailer Wiring Harness Fits 2012 Chevy Malibu LTZ
    The connectors on the taillights of the LTZ models of the 2012 Chevy Malibu are different which prevents the # C56027 from fitting. The Hopkins # 46255 is designed to fit your LTZ.

  • Left Tail Light on 2010 Chevy Traverse Stopped Working After Installing Trailer Wiring Harness
    Trailer wiring harness # C56027 is a T-connector, a pass-through device that doesn't draw any power itself so the only way that it could be causing the tail light to not work is if a pin inside one of the connectors is bent or broken, dirt or corrosion is in one of the plugs, or the unit does not have a sufficient ground. You will want to unplug the connectors and check the vehicle side and trailer harness connectors to see if any pins are damaged or if anything is dirty. For the ground,...

  • Recommended Trailer Hitch And Wiring For A 2003 Chevy Tahoe
    Hey Joe, For the trailer wire harness I recommend the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236. If you haven't picked out the trailer hitch yet then I recommend the etrailer Trailer Hitch Receiver # e26KR if you're just looking for a Class III trailer hitch. *Note: this does not fit models with canister on rear passenger side frame rail.* If you're wanting something a bit heavier duty we also offer a Class V Curt Trailer Hitch Receiver # C15324.
