Greetings, the plug was easy, the play not so much. After renting a bike trailer from U-Haul the park lights didn’t work. Returning home I bought a flat four plug tester, park lights weren’t working. I wrote their web site to give them a chance to correct it before this review, no response. Not very pleased…hopefully I’ll hear something now

There are a couple of reasons that this harness would not be working. Have you had a chance to check the wires on the vehicle side, as well as the trailer side? If not, I would highly recommend using a circuit tester, like part # PTW2993 to test the wiring on both sides. Also, be sure to test the wiring going to and from the converter box. First test the wires going into the converter box. If they are fine, move onto the wires coming out of the converter. If you have power coming into the converter but not out, then we will need to get a replacement out to you, because the converter is bad. Let me know if this helps.

On '93 Honda Pilot, installed wiring harness in about 20 minutes. Also installed Draw-Tite tow bar (75599) and Tow Ready 4-Flat Universal Mounting Bracket (118149) to stow wiring harness plug. None of the wiring harness is visible from rear of vehicle with only 4 - 6 inches underneath. All of the wire is tucked away in rear threshold where I found two grommets leading underneath the vehicle. After cutting out a space in the grommets for the wire harness to run I reinstalled grommets back into place. Very neat install, wire is snug behind threshold where plug was located. Worked as advertised.

No problems at all one year after the install.

I didn't have to pull off the rubber door gasket but I did have to remove the plastic piece across the back which broke the plastic fasteners. I think I needed a Phillips screwdriver and 10 mm socket wrench. I used the double stick tape that came attached to the module and didn't bother with the screw, where it is located I don't think is going to move. There is a cigarette lighter socket that should be removed before pulling the panel out but even without taking that step it wasn't hard to straighten the tabs and plug it back in to the connector.

About a 20 minute job, not difficult.

Still working well after a year.

I had an old wood stove that needed to be transported to the metal scrap heap at the local landfill. The hitch and drawbar were already in my possession but I needed trailer wiring for a rental trailer. I looked at the trailer rental store's offering of a generic harness that involved splicing as part of the installation process; I suppose it would work just fine but this product seemed to be much easier to install. After the removal of three trunk lining fasteners I had access to the wiring plug that is standard issue for my Honda. I connected the etrailer mating half of the plug to the Honda plug, fussed with the location of the "box" and the wiring a little and I was done except for verifying with a voltmeter that all the functions were working. When not in use the bulk of the wiring is hidden in the spare tire well underneath the trunk floor panel.
This harness works just fine on my 2000 Honda V6. I'm happy.

The trailer wiring harness was a great solution and I have attached some pics of how i ran the wires for the installation. I found some access holes in my 03 Honda Pilot to avoid pinching the wires in the liftgate.

Such an easy installation. Directions were spot on.

I have been using this harness for a year with a small utility trailer and my Honda CRV. Easy installation with very clear photos and instructions worked great for me. Quick response and delivery from etrailer was great.

@Charles Great, thanks for checking in!

The hitch is compatible to Honda CR-V (model 1998) and apparently fits well. One must be careful to adjust the exhaust system and check the engine rotation for smooth operation, otherwise it could produce noise. The electrical wiring is easy to install with little effort. My purpose is specifically to haul garden and landscaping items and this is a worth spending.



by:

The trailer wiring harness worked perfectly. Getting the panels off my Honda Element was a job but the wiring harness worked as intended.

2006 Honda Pilot

I installed the 4 pin quick connect harness and the ETBC7 universal 7 pin kit on my 2006 Honda Pilot EXL to get it ready for towing our popup camper. The instructions are clear and the installation was fairly easy but did take over 4 hours start to finish. Connected to a tekonsha voyager BC taken from our old tow vehicle. The installation looks professional, I know it was done right, and saved about $200.

Honda CR-V

Haven't fully tested it, but installation was easier than anticipated. I recommend watching the video for options for routing the wires to the storage compartment in the CR-V. I cut a small slit in the corner, closest to the bumper, of the storage compartment and pulled the wires through. Honda provides a great place to store the wires! -A.

2006 Honda CR-V

This hitch was exactly as advertised and fit my CRV perfectly!!! Used spray bottle with soap & water to lube the two upper muffler rear hangers and they slid off with little prying needed (did not need to remove the lower hanger in front of muffler). etrailer's installation videos for installing both this hitch and corresponding 118336 wiring harness were spot-on and very helpful (also a good video on the Curt website). Took my time tightening the hitch bolts to specs which was a bit awkward until I thought to use my ratchet extension bars. Maybe the easiest "car repair" I've ever done, and probably saved a lot of $$$ doing it myself. If you can change your oil, you can do this installation no problem!
Also, etrailer promptly shipped this product for free (thanks, guys!) and it got here a day early. GREAT COMPANY! When I save up enough to buy roof rack rails in the near future, I'll be back...



by:

Items were packed pretty well, nothing seemed to have moved or been damaged during shipping. Part fit as good as OEM, all hardware was correct and the harness fit perfectly.

Product functioned as expected. The fact that harness can be stored in vehicle is good. Thanks

Fastest delivery I have ever had. Ordered Wednesday at 5PM, arrived Thursday at 3PM. I'm only a couple hundred miles from Wentzville, but still, excellent. The hitch receiver (2008 Pilot) installed quickly and easily. No need to remove spare or lower muffler. I supported the left end on a large cooler and quickly maneuvered the right side above the tail pipes. The mounting holes were right on target. I had to tap mine to remove rust, but that's easy as well. The wiring harness was also a snapto install. Simple to plug into existing fitting and the wiring box tucked away nicely beneath the trim as advertised. There are options about what to do with the wiring tail and trailer connector. I chose the method shown in the video...leave it rubber-banded in the storage well. Others have run it outside through available holes, but I did not want to leave it exposed to road grime. etrailer's videos were very detailed and shown on my specific vehicle for both the hitch and the wiring harness. Good values as well. If I were Draw-Tite (or Curt) I would include a complementary rubber plug with their logo...cheap advertising.

2004 Honda Element

This was pretty easy to install and works great on my trailer. The installation instructions were not exactly correct for my 2004 Honda Element AWD Ex. The number of screws and plastic plugs that needed to be removed to pull the passenger side trim panel clear to access the vehicle's connector did not match the instructions. I found it essential to unbolt the right rear shoulder strap from the floor of the vehicle. This allowed much better access to the wiring behind the panel to plug in the connector for the harness. The adhesive on the black box that comes with the harness was weak, and didn't stick to anything behind the panel.

Yes I still like them!



by:
2003 Honda Pilot

Great product! Installed on a 2003 Honda Pilot. Easy installation. Removed trim plate at rear of cargo area without any tools. There was a plug under the plate that you simply plug the wiring harness into. I leave the wiring harness in the storage area for the head rests when not in use. When I need it I pull it out connect it to my trailer and gently close the rear tailgate on the wires.

Yes I am still completely satisfied with both the hitch and wiring harness.



by:
Honda Pilot

I wrote about the wiring harness in my review of the hitch installation. Many talked about how difficult it was. I followed the directions for my Honda Pilot and found it very quick and easy. It stows in the compartment with the head rests and I pull it out when I need to hook it up. Pretty simple. If only it could be accessible right at the receiver without hanging out the rear hatch it would look a lot better. Picky, picky, picky. But, that's why I gave it a 4 out of 5. The etrailer staff were extremely helpful and quick to respond with precise info. Thanks folks.

The wiring harness plugs right in to the wiring in the aft area of the Honda. It is there as a backup if I need to transport my Demco dolly behind the Honda it usually carries behind my bus. It was also shipped with the hitch and receiver..new in the box and well packed. I'm very satisfied with the products and service from E=trailer.

Had weird acting trailer lights for quite awhile. When I checked voltages at the vehicle I noticed low voltages for one of the TS. I suspected the 4 way adapter that was installed in 1999 Odyssey. I purchased this one from eTrailer, hooked it into the van and it fixed the issues. The trailer lights are now rock solid. I guess the TS converter on the old one had an issue. All is well now.
