Plug-and-play custom harness gets turn and brake signals on your towed car with no hardwiring or splicing, and no effect on your warranty. The built-in diodes protect your car from electrical feedback.
Features:
Notes:
A combined lighting system, or 2-wire system, uses the same light bulb to signal both braking and turning. (In other words, the car signals a turn by flashing the brake light.)
A separate lighting system, or 3-wire system, has the brake signal and the turn signal light up independently of each other. Typically, the turn signal is amber.
To keep the separate lighting system on your car functioning properly while you're flat towing, add a wiring converter (118158 - sold separately) and 2 additional diodes.
If the engine is off and your car's brake lights illuminate when you press the brake pedal, you need to install a brake light relay (RM-88400 - sold separately) with this kit. Without a relay, your car's brake signal will override the turn signal sent by the RV when you are slowing down to make a turn, creating a potentially dangerous situation. Other drivers will see that you're slowing down, but not that you're making a turn. With a brake light relay, you can signal both and travel safely.

Works great. Install instructions were straight forward,
I modified mine to a 5 round to facilitate the plug on my motor home. Really happy with product after 1 year.
Did an excellent job tracking and shipping my order on time.
Thank you
Ordering and shipping was fast and easy. Products arrived in good condition. I haven't installed them yet, but it all looks as advertised. Not my first order with etrailer and the customer service was outstanding as always. Why anyone would order from any place other then etrailer I cannot fathom.
The tail light wiring kit for our 2014 Honda CRV came complete with good instructions. It was challenging to get the wiring through the chassis from front to the back, but accomplished with patience and good floor jacks. The system has performed as expected. We are thankful for the Hopkins kit.
Well made and easy to install. Again the videos are great.
After one year of using, I am very happy with my purchase
Good quality product. Easy to install on my CRV. Video by etrailer was very helpful. Love the fact that all I need to do now is plug the harness in to my RV. Because my RV connection is a 7 pin connector, now I have to rewire the CARB plug to a suitable 7 pin connector to go with my Roadmaster tow bar

Great! Toad lights work every time plus I now have a 12 volt feed to my toad battery. No more worries.
This wiring harness works great for operating the brake and turn signal lights on my 2012 Honda CRV using the existing bulbs. This is the second one I have installed. The first one I installed had the diodes burned out when I bought a new car battery, and the installer shorted the positive to the negative with his wrench when tightening the cable to the battery post. So, be careful about that.

After a year, it still works perfectly.
This was exactly the plug and go harness for flat towing that I had hoped for! The connections were easy, but running the harness from rear to front was more challenging; just the nature of the underbody. The installation video is excellent. I have used this wiring for the past year..no problems. Would definitely reccomend.

It has been great-no problems whatsoever. In fact, I have recommended it to others.
I was not sure that I would be able to do this installation by myself until I looked at your videos. With your help, I had the installations along with the wiring completed in two days. Thank you for providing the video instructions for us. I would highly recommend etrailer.com to anyone who wants to have a hitch or baseplate installed, but thinks the cost of installation is to high right now. I saved nearly $1000.00 doing it myself, and I know that it was done the correctly. I received the items in good condition and in a timely manner. Thank You!
After watching the installation video I found this tail light wiring kit easy to install and added it at the same time as my tow bar base plate. For a little extra protection I routed the wiring harness through a wiring loom which added a little extra time, but overall should be worth it. The wiring system works great and I highly recommend it.
Product arrived in a timely manner. I watched the installation video and was able to install it in short order and it works! This is a well designed product and came with everything that was necessary.
Thanks etrailer.com,

Still working fine. Thanks again for a good product.
I purchased a wiring harness for our 2014 CRV so that I can use the vehicle as a dingy behind our new 2016 Thor Miramar. I installed the wiring harness myself. Been using it for a year now and have not had any problems. This is truly a plug and play device. You simply unplug the tail light connectors and insert this in-line and you're good-to-go.

Base plate video was very helpful, did in less than 3hours. Wiring for Honda CRV was easy to install.
All products were delivered on time. Would order any other products needed from etrailer.
Thanks
Product was exactly as described and matched my 2014 CR-V light system exactly. The installation video was very helpful and I was able to do the work fairly easily with only the use of 2 auto ramps on the drivers side (ds), although all 4 wheels up might have been easier. I had installed a trailer hitch earlier which hindered the crossing to the passenger side; however the porthole I had made for that installation on the ds aided in getting the wiring to the top of the ds rear wheel
I received the HM56304 towed vehicle tail light wiring kit very quickly. After watching the Video a couple times I was able to install the kit in about 2 and 1/2 hours on my 2013 Honda CR-V. It is all plug and play so the only hard part was routing the wires from the rear of the CR-V to the front under the car. I'm old and not small. I used roll on ramps in the rear and then moved them to the front to finish the routing. This custom kit is much better than the generic wiring kit I used on my last TOAD. The video was very helpful.
This taillight wiring kit for my 2014 Honda CRV was perfect and easy to install without splicing original wires, when running wires to under vehicle make sure to keep away from any turning components or heat sources, I ran mine along the edge of car around wheel wells tucked inside of trim and along the rocker panel to the front under side of radiator zip tied along the way.
Installed my self and I'm 70 years young. Took about 4 hrs. total time. Installed on a 2014 Honda CRV. Was dreading removing the famous 4 yellow clips on the front grille everyone was complaining about but pulling the grill the way the video shows is the way to go. I thought some of the plastic clips would break but none did, but you must be careful.
Shipped and arrived in just a few days and on time. Box was torn open but everything inside was fine.
The fit was perfect and no drilling was required except for installing the brakeaway switch which was not part of the kit anyway.
It was by far the easiest wiring kit to install plug it in no fuss ! Honda CR-V are not the best to work on because of the under carriage being all plastic. The VIDEO is the only way to go as far as route of harness and installing the only thing I did different was put flex tubing around harness for extra protection or peace of mind !!!
I'm telling you etrailer is the only way to go they have the best staff to get you what you need when you need it and products top of the line!!!
The diode wiring kit performs great on my 2017 Honda CRV.
I do continue to have a dead battery after towing because e-trailer suggested pulling the incorrect fuse.
No one seems to know which fuse keeps the battery from dying. Not #14 and not #19. Still waiting for the correct fix here.
Easy to install and works as expected. This has been installed for over a year and have proven to be problem free. Just be careful when plugging and unplugging to the 4 wire connector. I did have to splice in a new connector but that was after many plug/unplug cycles.
this wire harness is a plug and play product easy to install with great instructions and great video on line. have used for over a year with no problems. also best price on the internet. thanks etrailer.
easy to install
I just received the Hopkins taillight wiring kit for our Honda CR-V. It arrived much sooner than expected and it was exactly as described in the etrailer.com description. I haven't installed the wiring kit yet but after viewing the excellent CR-V installation video I don't expect any problems. I have used etrailer.com for a number of purchases and every transaction was superior in service and execution.
perfect fit and function plug and play easy install
