Making memories doesn't start when you reach your destination; it starts at the very first mile of your journey. Wherever your road begins and wherever it takes you, Bring It® with the power of CURT.

CURT custom wiring provides everything you need to connect your vehicle's electrical system to a trailer. With plug-and-play connectors, a custom wiring harness easily integrates with your vehicle taillights to provide a standard trailer wiring connector, typically in the form of a 4-way flat.

This custom wiring harness features a vehicle-specific design to perfectly fit certain years of the Honda CRV (to verify vehicle compatibility, see the CURT application guide or use the Vehicle Lookup on the CURT website). It uses OEM-compatible connectors to "T" into the vehicle's taillight assembly and provides a standard 4-way flat output to power the taillights, brake lights and turn signals on your trailer.

To complete this custom wiring harness, it comes with a rubber dust cover. This cover keeps the connection points clean and well protected when the connector is not in use. Once installed, the connector can also be conveniently mounted on the vehicle's trailer hitch receiver tube, using a CURT Easy-Mount connector bracket. The bracket mounts onto the trailer hitch with no drilling required, and its powder-coated steel construction provides a solid attachment point for plugging in the trailer wiring.

    Something Different About 2015

    Hi! I watched a video on You Tube as to how to install part #56158 in a 2015 Honda CRV. When I went to do it I found that the connector on the harness doesn't match the white connector under the lower rear panel. Based upon the reviews above apparently there is a blue connector under the UPPER rear panel. Will have to give that a try. One suggestion is to have a close up of the connector in the photos of the product because I am not sure if what I got is actually a part #56158 even though the package says that it is (the reason I say that is because the connectors don't match) I have installed other Curt Manufacturing products on 3 previous vans without a bit of trouble.

    Installation hint on 2016 CRV

    Once I found the blue connector, the installation went smoothly. One item that other might find helpful: Instead of having the wire and plug loose in the trunk, as shown in the installation video, there is a way to feed it down and mount it beside the bumper. There is a large round rubber seal on the side wall with a corrugated wire cable running through it. The wiring plug doesn't quite fit through the metal hole. Filing small notches on opposite sides of the hole with a round file allows the plug to be feed through the side wall and then behind the bumper to the hitch receiver. Some chalking needs to be used to get a good seal on the rubber plug in the side wall.

    Connector under the upper panel

    initially I found the long, white connector, which is where the video and the instructions say the blue one should be. Another review helped me find the location of the blue connector. The instructions should include the possibility of this variation.

    trailer wiring harness for 2012-2014 Honda CR-V - part# 56158

    I give this wiring harness four stars because of the complications that arose during installation. I haven't used it yet but sure hope that it works after the hassle involved with installing it.

    Contrary to the 'Does not fit newer 2013 CR-V models' review, the wiring harness does in fact fit the 2013 and 2014 CR-V's. I own a 2014 CR-V and ran into the same problem as the above mentioned reviewer. I couldn't find the blue connectors at first. The current Curt wiring harness installation video for the 2012 CR-V is outdated for the 2013 and 2014 models. This youtube video - - shows that you need to remove the upper rear trim panel that goes around the triangular back window as well. The blue t-connector you need to attach to is under that upper panel and you cannot see it by only removing the lower rear trim panel.

    Several important things that the Curt video misses for 2013 and 2014 models are outlined in the youtube video above. They include: 1) the two fasteners holding the threshold in place are push-pin fasteners with center releases. Don't just pull up on them; they will break. You need to push down on the center of the pin to get them to release. The same goes for the cargo hook that needs to be removed. 2) The trim panel just behind the driver's side rear seat also needs to be removed. Don't worry; this is probably the easiest thing to do in the entire project. 3) The youtube video mentioned above shows removing the screws mounting the second row release seating handle to the body of the vehicle. I suggest following the Curt video for this and leaving the handle mounted to the body because it will help in figuring out where to mount the black converter box so it's not in the way. I will also say, the location of the t-connector behind the upper rear trim panel makes it very difficult to find a flat location to mount the converter box. 4) The last thing I will mention is something that neither installation video discusses. It is INCREDIBLY DIFFICULT to get the push pin that is attached to the top, inside of the upper rear trim panel to go back into the hole above the triangular window! I consider myself very mechanically inclined and creative and the only way I could come up with doing it would be to break the ceiling material or remove the ceiling entirely. After messing with it for nearly 30 minutes I finally decided to simply remove the push pin and the trim was much easier to get back into place. Feel free to try and get it back into the hole but know that it looks just fine even if you don't.

    I hope this review helps, no one else goes through the frustration I did, and Curt updates their video for the newer models of the CR-V.

    Does not fit newer 2013 CR-V models

    Have a newer (May 2013) model CR-V and this harness no longer fits. The car no longer has the blue connector, but a longer, flatter connector.
