Once installation is complete, the 7-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 7-way connector itself - to help prevent corrosion.

Service and delivery were great. I had asked a question regarding fitment on my vehicle and the folks at eTrailer answered my question quickly. I've since ordered tires and wheels with similar results. I'll continue to use eTrailer in the future.

Plugged right into the existing wiring. Wires were plenty long to get to plug mounting point. Have not yet checked if it is wired correctly. One minor manufacture problem. When Curt put the cable into their package they folded it up so tight that it broke the outer wire protector in several places. (At every fold point.) I had to black tape the entire protector to keep the pieces together. Not a big problem but a simple problem to fix if the manufacturer rolled up the cable instead of folding it up.

Perfect fit for my XT5, just plain plug and play technology. Thanks to Anna D for matching this wiring harness up.

  • If OEM Brake Controller Wiring was Bypassed for 2020 Cadillac XT5 Can it be Left Unconnected
    If you ran the blue wire from the Curt # C51170 to the blue wire of the 7-way kit part # C56326 you would not need to run anything to the brake controller wiring you mentioned as it would be effectively bypassed.

  • Is a Converter Needed for the Curt Wiring Harness On a 2017 GMC Acadia
    The Curt T-Connector Vehicle Wiring Harness part # C56326 is a fit for a 2017 GMC Acadia and there won't be any additional parts required such as a converter. The reason for this is because the Acadia's all have the factory tow package so the converters are already built-in and all you'll need to activate the trailer lights is the correct pigtail such as the on above. Please note, you will however need the Mounting Bracket and Installation Hardware part # PK12711U.

  • Recommended 7-Way Wiring Harness for 2021 Chevrolet Blazer RS
    In order to get a 7-way connection on your vehicle you should be able to use the factory connector you are talking about which has the connections for your current 4-way and also a 7-way. I recommend the # 118276 Tekonsha T-One Vehicle Wiring Harness. This custom wiring harness will plug into the OEM wiring harness where your existing 4-way is plugged in right now. No additional modification should be needed for the 7-way connection to work properly. I recommend the Tekonsha over other...

  • Will the Curt Trailer Hitch Receiver C13418 Fit a 2020 Chevrolet Blazer RS
    The Curt Trailer Hitch Receiver part # C13418 is indeed a confirmed fit for a 2020 Chevrolet Blazer RS. In fact, I installed this hitch personally on a 2019 Chevrolet Blazer RS and there were no changes from the 2019 to 2020 model year so I know it works. I also confirmed this with Curt as well just as a precaution. If you will be towing then you will also need a trailer wiring harness, the Curt T-Connector Vehicle Wiring Harness part # C56325 if you need a 4-way or part # C56326 if...

  • Comparing the Curt and Draw-Tite Trailer Hitches for a 2019 Chevrolet Blazer
    The Draw-Tite Class III Max Frame Receiver Hitch part # 76023 and the Curt Class III Receiver Hitch part # C13418 are both excellent options for a 2019 Chevrolet Blazer. I recommend going with the Curt Class III Receiver Hitch because it will be much easier to install than the Draw-Tite Class III Max Frame Receiver Hitch. The Draw-Tite Class III Max Frame Receiver Hitch requires that you remove the rear bumper fascia whereas the Curt Class III Receiver Hitch just requires that you lower...

  • Best Trailer Hitch for a 2019 Chevy Blazer All Models Including RS
    The best trailer hitch for a 2019 Chevrolet Blazer (All Models Including RS) is the Curt Trailer Hitch Receiver part # C13418. I place this over the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76023 because it will be much easier to install. The Draw-Tite hitch requires removal of the entire rear bumper fascia which will take upwards of two hours whereas Curt hitch really just requires you to lower the exhaust a bit which will only take around forty minutes or so all said and done....
