This custom-fit T-One connector plugs into your vehicle's 12-pin wiring harness located behind the passenger's-side kick panel.


Location of OEM connector

Once you've plugged in the 12-pin connector, plug the 4-way harness in beneath the vehicle, behind the driver's side rear bumper


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

Video Transcript for Trailer Wiring Harness Installation - 2008 Nissan Frontier

Today, on our 2008 Nissan Frontier, we're going to be taking a look at and showing you how to install the Curt T-Connector Vehicle Wiring Harness, part number: C56225. Here's what our wiring looks like when it's fully installed. It is going to stay on the outside of our truck at all times, and it will be hanging here ready when we're ready to tow. It's going to give us a four-pole flat, and it's going to provide us all the required lights to go down the road, such as our taillights, brake lights and turn signals. Now, this harness is a two-piece system. This section of our harness is going to attached to the back of our frame rail, while the other section is going to be attaching to the inside of our cab to the existing wiring. Now, let's go show you how we get it installed. To begin our installation, we're going to come to the rear of our vehicle and come real close to our spare tire on the inside of the frame on the driver's side. We're going to have two connectors here on the inside of our frame rail, and we're going to want to find the six-pin connector right here.

Now, it's going to have a cover on it and there's going to be a small tab right here. If we push in on that tab, it should release the cover. We can pull the cover off and expose the pins on the inside. Now, we can grab our harness, and this is going to be the section that's got the four pole on the end of it. Now, before we connect this, I'm going to put a little bit of dielectric grease into my connector, and that's going to help keep out some of the moisture and help with any corrosion that might be building up. We're going to go ahead and plug it in, make sure it locks into place.

Now, for right now, I'm going to leave my harness sitting here, because we're going to need to go to the inside of the cab on the passenger side. Now, we're going to need to remove this threshold panel here, then we can gain access to the kick panel back here. I'm just going to slightly start pulling away on the panel to pop it loose, then we can go ahead and set it aside. Now, in order for us to remove our kick panel, we're going to have a fastener right here. Ours is a little loose, but we're going to go ahead and unthread it by turning it to the left. Now, if yours isn't that loose, you can take a flathead screwdriver and put it in the slot in the center. We need to take our panel and just kind of twist and pull away, and the clip right here at the top and bottom should pop out. Behind here, we're going to have a lot of wiring harnesses and connectors.

We're going to be looking for the 12-pin connector that's going to go inside this end of our harness. Now, most of the time, if you reach back where most of your wires are, it will be right there. Right here, behind a lot of the other harnesses. Now, before we connect this, we're going to take the relays that they provided in our kit, we're going to have two blue ones and one rather large brown one. Now, the brown one, we're going to connect to the brown end on the other end of our harness. We're just going to line up the pins and put them in place.

We're going to make sure it locks into place. Then, we can do that for the other blue relays, they're just going to line up. These relays are the same, we're not going to have to worry about which one is which. We're just going to line up the pins on our relay, and connect them in place. With the relays in place, we can go ahead and find our connector, and we can plug it in. We can take our harness and all the relays, and we're going to actually tuck all this behind everything else and this is going to stay behind the panel that we just removed. If you need to, the kit does provide you with some zip ties so you can tie your harness up; but I think we'll be able to tuck everything in nicely, and it will be hidden behind the panel where we won't need it. Let's line up the tabs in our panel here, pop it back in place and replace the fastener. Now, we can line up the tabs in our kick panel here. Now, I'm just going to zip tie my excess trailer wiring to my hitch here, that way it's out of the way, but I'll also have my wiring available whenever I need it. I'm going to go ahead and test my wires, here I got a four-pole tester. Now, if you don't have one of these, you can pick one of these up on our website using part number: I26. I'll plug it in and now I'm going to grab an extra set of hands, so that I can start running our lights, and we can make sure that is working properly. Can you turn on the headlights, please We can see those are working well. Now, the left turn signal That's working. Now, the right turn signal Okay. Now, finally, the brakes Now, the brakes and the turn signals Looks like all our lights are working. Now, the last thing we need to do, is go ahead and slide our dust cover over a four-pole end here. This is going to help keep out some of the moisture and debris from getting inside the connector; but also, I'm going to use it to attach it to my hitch, that way when I'm not towing, it's right there and I don't have to worry about it dangling down. That will finish up our look at the Curt T-Connector Vehicle Wiring Harness, part number: C56225, on our 2008 Nissan Frontier.

I installed a curt hitch, curt T-connector wiring harness and flat tralier hitch holder. All were easy to accomplish and went quite smoothly. At seventy six, I was quite proud of myself. Bit actually, the products were great and easy to work with as was the service. The hardest part was crawling underneath the vehicle at my age. Thanks so much for your service, which was quick, your product, which was great, and your guidance, which I greatly appreciated and used. Great videos. Sorry no pictures as you are asking me to be too technical. 304405

The Curt trailer hitch and wiring harness fit perfectly. I'm 74 years old and only needed help because the hitch had to be angled to get above the exhaust system to the mounting site. the whole installation took only 30 minutes . Everything lined up perfectly. It gets a 5 star, excellent rating from this senior in PA! 430411

I purchased a wiring kit and hitch ball for my new 2016 Nissan Frontier. The truck does not have the factory tow package. However, it does have a class-II tow bumper and Nissan sends them all pre-wired for lighting, but not activated. The kit I ordered from etrailer had everything I needed to activate the factory wiring harness (a couple of simple, plug-in relays) and a 4-pin flat plug that also just plugged into the factory pigtail at the rear of the truck. Added a bracket for the flat plug (also from etrailer) and in about 30 minutes I was good to go. I consider myself above average in the shade-tree mechanic stuff, but I think pretty much anyone could do this installation. It was simple and straightforward. They even have a very helpful video of the install procedure online. Based upon this purchase, I would consider etrailer for any future purchases I may have for trailering products and their shipping was fast and well packaged too. 322737

I purchased the Curt trailer hitch and wiring harness for my recently purchased 2015 Xterra. Plan on towing 3000# max utility trailer. Shipment arrived very quickly after placing order, well protected in box. Install was a breeze. Took more time rounding up the tools than installing the hitch and harness. Did not need to drop the exhaust to install hitch. Nissan installed bolts are VERY tight - required 24" breaker bar to loosen. Called about harness installation. On hold less than a minute, great response. Hooked up to trailer and all lights worked. Highly recommend these products. 218835

Receiver and wiring kit for 2019 Nissan Frontier - everything fit perfectly and was a piece of cake to install. I would recommend watching the videos for each - excellent walk-through of the process plus, it will make sure you do not damage the interior when installing wiring harness/relays. I would also recommend use of a torque wrench as shown on the video. Both installations combined took less than 1 hour. Items arrived very quickly - in 2 days from order. Very pleased!! 645053

The wiring package was an easy install. I initially looked at the wiring video and then followed the instructions that came with the product. I was able to complete the wiring within 20 minutes. The hardest part was taking off the front passenger floor panel and getting access. This was the first time that I had ever taken off a panel. After that was completed hooking up the various wires was a breeze. 639430

The etrailer wiring kit installation video was great!!! It was very thorough and accurate. My truck issue was that the trailer running lights did not work. Using just the wiring harness at the hitch allows the brake lights and turn signals to work, but the etrailer wiring kit with the relays was needed to allow the running lights to work. There are an amazing amount of other videos out there on the same subject and they all proved worthless/wrong with their fix for running lights not working. Even the Nissan dealers (2) and a 'seasoned' 30 year trailer sales owner did not know the fix. This wiring kit supplied by etrailer has my running lights finally working. This Company has great follow-up, service and as stated before excellent videos of the installations. 544777

Do you have a question about this Custom Fit Vehicle Wiring?


  • Troubleshooting No Power at Factory Trailer Wiring Plug on 2014 Nissan Frontier
  • If you are not getting any power at the factory port where the Curt Wiring Harness # C55441 plugs into, this actually may indicate that your 2014 Nissan Frontier is not equipped with the factory tow package. The existing Curt harness will still plug into the factory port like you see on your vehicle, but without the tow package you will still need to add a relay harness for the port to become active. This relay harness is included with the Curt T-Connector # C56225. It is not available...

  • Relay Harness Needed for 2019 Nissan Frontier
  • I do have a solution for you, but unfortunately nobody currently (as of January 2019) sells just the harness for the relays out of the T-One Kit # 118266 that you referenced. Since you already have the 7-Way wiring and connector the next best thing would be to get the Curt T-Connector # C56225 and install that relay harness which is essentially the same thing. This is just at a lower price point because it is for a 4-Way which is less complicated than the 7-Way wiring harness. I have...

For a trailer hitch receiver that is compatible with a 2010 Nissan Xterra, I recommend using the Curt Trailer Hitch Receiver part # 13514 over the Draw-Tite Max-Frame Trailer Hitch Receiver part # 75291 as the Curt Trailer Hitch Receiver is rated for a high capacity in...

Both the 4-Way and 7-Way options will be pretty simple, plug-and-play type installations, so your best bet is to simply choose the connector that matches what you have on your trailer. If your trailer just has a 4-Way connector, then I recommend the Curt T-Connector Vehicle Wiring Harness # C56225. If the trailer...

If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If the ball mount kit does not include a ball mount...

The maximum GTW for this hitch is 5,000 lbs. and the tongue weight capacity for this hitch is 500 lbs.

  • Running Lights Not Working After Installing Wiring Harness On 2015 Nissan Frontier

This is located under the driver side dash to the left of the steering column as shown in the attached photo. Nissan did install the relay on some vehicles but failed to do so on others.

  • Are Relays Needed to Install Trailer Wiring in 2006 Nissan Frontier
  • If your 2006 Nissan Frontier does not have the factory trailer wiring it would need relays to activate it. For that you would need the part # C56225. If you have the relays already all you would need is the part # HM43575. If you look behind the kick panel in the passenger side of the vehicle you will be able to see if the relays and breakers are there.

For a hitch you would want the Curt hitch part # 13241 as this has also be confirmed as a fit for your vehicle.

If you need the relays and their harness too then instead use the complete kit # 118266. The 3 relays alone are offered as # C57000. These relays do not concern the trailer brake circuit, only trailer 12V power and lights. For a trailer brake controller I suggest the Prodigy P2 proportional controller # 90885 and the matching...

Otherwise, there are a host of potential issues that may have caused only some of the lights to work after you installed Wiring Harness # C56225.

  • Parts Recommendation to Install a 7-Way Trailer Wiring Harness in a 2015 Nissan Frontier
  • Since you do not have a factory trailer wiring you will need to start with a 4-way (if you do not have one). For that you would want the # C56225. From there you would need to convert the 4-way to a 7-way so that you can install a brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. If your trailer does not have brakes instead of the # ETBC7 you...

  • Recommended Trailer Hitch and Related Items for Towing with 2008 Nissan Xterra X
  • We offer several choices in a 2-inch Class III hitch for your 2008 Nissan Xterra X and you can see these by clicking on the link provided. I recommend the Curt # 13514 because it has the highest tongue weight capacity (400-lbs) AND has the lowest cost too. You will want to check your owner's manual for confirmation of the vehicle's tongue weight capacity. You'll also need a wiring harness for your trailer's lights. Use part # C56225 if you do not have the factory tow package or part...

  • Replacement Blue Running Light Relay for a 2011 Nissan Frontier
  • It does sound like your 2011 Nissan Frontier is missing one of the blue relays; the one that is for the running light circuit. We do have the blue relay by itself. It is # 38666-1.

  • What is Needed for a Complete Tow Package for 2005 Nissan Xterra 4wd
  • I recommend the Curt Trailer Hitch # 13514. The class III hitch has a 2-inch receiver, 4000-pound towing and 400-pound tongue weight capacity and bolts onto your Xterra's frame with no welding required. You will also need a wiring harness. Which harness you require depends on whether your vehicle comes with a factory 7-way connector, a factory 4-way connector or without a factory 7-way or 4-way connector. If your vehicle comes with a factory 7-way connector, you will need part # 118266. To...

  • 2005 Nissan Frontier Trailer Wiring Comparison
  • Looks like you are asking about the difference between the Curt trailer wiring harness part # C56225 and the Tow Ready part # 118525. Essentially these are the exact same harness made by two different companies. Tow Ready and Curt are both excellent companies that make quality trailer wiring harnesses. Because of that I would go with the Curt since it is priced better.

  • Replacement Relays For Trailer Wiring Harness On 2008 Nissan Frontier
  • I do not know of a way to check a relay and see if it is good other than to use a new relay in the wiring. For your 2008 Frontier, a wiring harness like part # C56225 uses three relays, so it could be any one of the three has possibly gone bad. We do offer the Curt Relay kit # C57000. This kit includes the two smaller Blue relays and the larger Brown relay.

  • 2009 Frontier XE Trailer Running Lamps Not Working After C55441 Trailer Wiring Harness Installed
  • There are two different Curt options for trailer wiring for your 2009 Frontier, # C55441 for vehicles that have the tow package and # C56225 for vehicles that do not. Both use the same pigtail with the 4-pin trailer connector that installs at the rear of the vehicle, but if you install the C55441 on a vehicle that doesn't have the tow package, the running lamps and the 12-volt accessory circuit will not work. Long story short, you need the # C56225 that includes the jumper harness and...

  • 4-Way Wiring Harness Bracket Recommendation for 2010 Nissan Frontier
  • The Mounting Bracket part # 18144 that you referenced would be a great choice for mounting the 4-way on your 2010 Nissan Frontier. This is a universal fit bracket that would install just as well on your 2010 as it would on a 2011 Frontier. I attached a link to the install video you mentioned as well.

  • Finding Brake Light Wire On Volkswagen Jetta For Brake Controller Installation
  • There are some vehicles that are hard to locate the stop light switch wire needed for a brake controller, and Volkswagen is one of those. Per my contact at our manufacturer, you may want to find the wire that leads to the third brake light. You will need to use a circuit tester like part # 40376 and find the wire that only shows current when the brake pedal is pressed. They were not able to tell me which side of the vehicle the wire can be found, but typically the wire can be found...

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2012 Nissan Frontier with 4-Way
  • If you have already installed the jumper harness with the 3 relays when you installed the 4-Way (# C56225 as an example) then you would just need # 118267 to upgrade to a 7-Way trailer connector. If you had not installed that jumper harness then you would need # 118266 which includes the harness and relays. To activate the trailer brakes you will also need a brake controller and wiring harness if you don't already have them. I recommend the P2 brake controller # 90885 because it is easy...
