Additional Information

A CURT custom wiring harness (also called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring.

Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT''s custom wiring harnesses come into play. Custom wiring harnesses plug into your vehicle''s electrical system using original equipment (OEM) connectors. Our custom wiring harnesses use two or more OEM connectors to plug in at the taillight assembly and provide a standard trailer socket to allow a trailer to be plugged into your vehicle''s power system.

This harness provides a 4-way flat connector socket and comes with a circuit-protected converter. It is designed to be a custom wiring harness for certain years of the Honda CRV (to verify your vehicle compatibility, see the CURT application guide at CURT custom wiring harnesses are long-lasting and quick to install. They come with dust covers to keep your connector clean when not in use and feature a one-year limited warranty to give you peace of mind.

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.
