T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

We purchased this for our 2009 Murano LE so that we could tow our boat (we have a single cab truck so with kids it was just impossible). First off the first harness we got was installed no problem just followed right along with the video and all was fine….until the lights were blinking all incorrectly. Long story short here is the deal. I called etrailer and told them what was going on, with no hesitation they put another in the mail. That is customer service. These guys deserve 10 stars but I’m limited to five. The new harness was just fine and we have used it multiple times a week for the entire summer. Not a single issue.

Thank you to etrailer for good products but mostly thank you for going above and beyond with your customer service. You’ve got a customer for life here.1369382

Ordered hitch to match car (year,model etc). Added [other] wiring to order, wiring sent was for later model, had to reorder & repurchase and could not return wrong harness. Paul responded quickly, received harness quickly. Had to have hitch professionally installed. $xxx extra cost after purchase of hitch and harness.1491035

The wiring harness looked perfectly intact and properly installed according to the video provided, but when it was time to finally use the product and connected to the lighting of a trailer it didn't work. It's been 2 years since I have ever needed it for the job is needed and I was using a Uhaul Trailer. I needed to inform a buyer that I wasn't able to ship their item to them and lost a potential client. I definitely would recommend if it functions immediately and not wait several year before realizing it never worked in the beginning.1269687

I recommend troubleshooting with the harness before considering the harness defective. With trailer unplugged from the harness you can check the ground and test the light functions with a circuit tester. This will be the quickest way to determine if it on the vehicle side or the trailer side. And proceed from there. We have a FAQ that can help.

Troubleshooting 4 and 5-Way Wiring Installations

I've installed other trailer wiring harnesses before so this time the installation was easy for me. It took more time to disassemble the panels in the back of my Nissan Murano (for the first time) and put everything back into its proper place than it did to hook up the trailer harness, secure all the parts and install the 15amp fuse in the fuse holder under the hood.657829

Videos made Every work perfectly as adv ertised.1469334

The wiring harness was exactly as described, but I have really brag on your installation video as well as your website. Both are 5 Stars. I’ve used a lot of websites to purchase products, but your is the best by far. Thanks again.1250645

Every item I've purchased from etrailer has worked in spectacularly. etrailer even let me return an item w/ out hassle... Now thats service! Always easy talking w/ their reps tho if I had to complain... Phone answer can be a wait sometimes. Otherwise I have no complaints about etrailer products or staff.1219937

This fit my 2013 Nissan marano perfectly. I used an old m12 bolt and cut the threads down the side with a cutoff wheel to clean the threads out. This worked perfectly.920865

Great service, received the hitch and the wiring harness sooner then expected.
They were the correct parts.
I read the reviews and tried to install the hitch without removing the muffler. It worked but you do need an extension for you socket set. The best part if installing were the videos that showed every step you needed to do. It made it simple.
The wiring harness went in easily and clipped as advertised. I would suggest they add a second self-tapping screw to mount the adapter and several ty-wraps to cinch down the wires coming across from the passenger side.
Over all, It was simple to install and looks and works great.

Courtney B in customer service was great, she even confirmed my order was delivered! Ordered the 87486 Hidden Hiitch with the T-One 118653 wiring harness for my 2013 Murano. Was delivered in 3 days. I chose this Harness because the max amp rating was the highest for my vehicle. Both pieces fit perfect, the videos were extremely helpful and made me confident I could do the install myself. The Harness directly connects to all factory wiring as shown in the video, the most difficult part is removing the interior panels. Which is not even that hard as it is shown in great detail in the etrailer video. It is a well built product with a custom fit for the Murano, if you need a Harness, this is the one!!229706

Harness is well designed, works flawlessly

First, ordered this wiring harness on a Monday afternoon and requested 3 days shipping, then my wife called and said we were leaving on vacation Friday at 9am, which meant if my harness didn't ship Monday, it wouldn't be here in time. Called etrailer and
Katherine promised to get my harness to me, followed up that it had been shipped, and followed up again that it had been delivered! Funny thing is, I just attended a seminar at work on the difference between a satisfied customer and and loyal one, and Katherine's superb service and follow-up has not only made me a loyal customer, but I will 100% recommend etrailer.com to anyone looking for car accessories.

Now to my harness. When it arrived I took it to my Murano, sat my laptop in the cargo area and pushed "play" on the installation video. Watched each step, paused the video, and did each step. The video was perfect and showed exactly what needed to come out of the trunk, and the little tricks for removing each piece. In 45 minutes myself and my 6 year old son had it perfectly installed and it works flawlessly, so glad I didn't give the Nissan dealer almost $300 to do the same thing!!

I would have attached a pic of the installed harness, but It's 100% hidden, just the way I wanted it.

Thanks again etrailer!!47608

Yes, this kit is confirmed as a fit for your 2013 Nissan Murano, as long as it is not the CrossCabriolet version. I have included a link to our confirmed products that fit a 2013 Murano for your reference.

Great products. Fast D 1331227

The harness arrived and fit perfectly in my wife’s 2009 Nissan Murano. This Murano has the power socket already in the back as well as the trailer fuse slot in its fuse box, so there was no stringing wire under the car and to the battery. The install procedure was essentially identical to the 2010 Murano video.

Very easy. It was harder to reset the car’s rubber door gasket if than to install the wiring. It took about 1.5 hours this first time but I could do it in 30 minutes next time. 739179

Installation was a breeze and it worked fine, however have not towed anything since.

quick delivery, great price. What can I say it's a wiring harness. I will do more business with etrailer in the future based on this order since it is the first time I have ordered anything of this nature and I am very satisfied with my experience. My rating of etrailer is EXCELLENT. Everything went exactly as described in the video. Thank you etrailer.384585

As good as day one.

The team and selection at etrailer.com is excellent and the Draw-Tite Draw-Tite Ball Mount Trailer Hitch Ball Mount purchased installed easily and the tech support team answered my questions in a timely manner and provided the support needed. I will certainly search their inventory for my future trailer needs.1017603

I wanted to thank you again for the quality of items you have. The item was easy to order and install. There’s so much stuff you carry that I’d love to order but I know where to go when I need to order. Thank you again. It’s nice to have a trailer hitch to pull whatever I need. You won’t be disappointed with your purchase. 651145

I’m still very happy with the trailer hitch I bought and installed. It has helped me in many instances. It’s great to be able to connect to my trailer any time I need to instead of asking someone else for help. Thank you again.

If you follow the video you can’t go wrong. Everything worked as planned. A second set of hands came in handy. Took our time and the entire install was about two hours.1309063

Easy install for the most part...I did have to use my own self-tapping screw in the vehicle; this kit had a REALLY short screw...maybe 1/4" long, so anything worthy of a ground is thick metal through sheet metal in the cargo area of a '12 Murano. Still, it's plug-n-play on the rest. Instructions were pretty easy to read. Some minor tool skills will be needed, but not much more than that. All connectors were there to connect between the tail harnesses and I mounted the signal booster box under cargo storage. I did use a couple more plastic wire ties beyond the two tiny ones the kit had to properly stow the wires. The harness 4-pin connection is supposed to run across the rear hatch seal, which I don't particularly like, but is sufficient. I will be running the harness with a 4-pin harness extension through a rubber grommet/boot in the forward cargo storage under-floor area (rear cargo) on the driver's side so I can mount it direct to the hitch without digging this thing out every time. Otherwise, I fixed a problem on the trailer side when nothing worked (checked power with a multimeter on my side and all was working). There are two fuses supplied, so make sure you install them both (on the harness and one under the hood in the driver's side fusebox). It did take a little time for the harness to come in, as well. Recommended product...especially for the price! No problems and have used for quite awhile now. I debated on buying the more expensive choice as I know how cheaper can net some...interesting--or not compatible--results at times, but glad I went with this one. Cheers, and thanks!424711

The service was great - very knowledgeable assistance. We also received the product in a timely manner. I previously bought a hitch from them and it was great. We would definitely buy from etrailer again.364535

We really like the products. We used the trailer to put our things on for a family vacation last summer and everything was great! We have recommended your company to a few friends who are interested in buying a hitch for their car and or a carrier. Thank you for taking the time to write and check in.

Like others, I was able to install the hitch fairly quickly without dropping the muffler. That does require a socket extension. Some blocking too hold up one end of the hitch while fastening the other end to the frame is also required. As another reviewer noted, the hitch side which attaches where the tow hook is removed didn't line up exactly. I tried to spread it in place with a pneumatic spreader without success. Could have removed it and banged it out with a sledge hammer but decided that the two 12M bolts I was able to place on that side would be adequate and I might weaken a weld joint by banging it out. Took far longer to hook up the wiring than I thought it would, but I was also aiming for a factory-install look - zip ties everywhere, running the power wire under the driver-side rear storage compartment, etc. I would have liked a little more length on the wires leading to the 4-pin connector. It only reached to the receiver after I fastened the wiring "junction box" to the car body underneath the driver-side tail light. A drop hitch in the receiver could require longer wires on the trailer side. Could have done with less length in the wiring going across to the passenger-side tail light. Working the power wire to the engine compartment without a car lift wouldn't have been possible if I'd eaten lunch - not a lot of clearance under a Murano! I ran the wire along what I believe were brake lines. A straightened coat hanger with nylon cord and a person looking down from above the engine compartment to grab things as I passed them up from beneath worked well. While I was somewhat disappointed with the hole for the 10M bolt not lining up with the car frame, I believe the whole package is well worth the cost and would never pay what was being asked for the OEM alternative.153603

Very simple instructions for the wiring kit. Took only 20 minutes to install after watching the video. Suggest routing trailer connection end through existing rubber grommet to keep wiring near trailer hitch just under the vehicle.614470

The manufacturer specifically designed this particular harness so the connector would be deployed from the interior of the vehicle when needed. This way, the connector is protected from damage when its not being used. The rear hatch of your vehicle has weatherstipping thats thick enough that the wire for the trailer connector wont be damaged as long as you avoid the latch area. You can certainly install the harness as you described, but the connector will be exposed to the elements.

The wiring harness was straight forward, and worked just as the installation video showed for my '09 Murano. The hitch fit perfectly. The weld nuts in my frame had rusted so that I had to tap the threads, which added a little time to the installation. I used a floor jack to lift the hitch into position while I got the bolts started. Otherwise, I would have needed a helper to get it up into place. Shipping took two days. There was a two-week lead time to have the local hitch shop do the work. I saved nearly two weeks of time and $160 by doing the work myself.252590
