Video Transcript for Curt T-Connector Vehicle Wiring Harness Installation - 2015 Nissan Pathfinder

Ryan: Hey, everybody. Ryan here at etrailer.com. Today on our 2015 Nissan Pathfinder, we're going to be taking a look at and showing how to install the CURT T-Connector vehicle wiring harness with a four-pole flat trailer connector. This wiring is going to allow us to connect our trailer to it and illuminate all the trailer's lights. Now, that's not only going to keep us safe while we're going down the road, it's also going to help keep us legal. Other motorists that are traveling behind you too are going to appreciate the fact that your lighting works, and they're going to know what your intentions are.Now what kind of separates this kit from some of the other ones on the market is that it's all plug and play.

You're just going to plug directly into your factory connectors and you're not going to have to worry about running any wiring up to the front of the vehicle or anything like that. Now in my opinion, once you get this harness in your hands and feel it, you can just tell that it's very well built and durable, and should last a very long time.Now this harness is going to put out quite a bit of power, and that's going to allow us to run all of our trailer lights, whether they be LED or even incandescent. Now as far as exactly how much, all of the lighting circuits, this is going to put out 7.5 amps, which that's good because that's going to guarantee us that we're going to use pretty much just about any amounts of lights that we want. Now the cap is also going to help prevent any corrosion, and it's also going to double as a hook. What I by mean by that is if you don't happen to have any bracketry to hold this in place, you can wrap this around your safety chain loop, put the cap on, and store it that way.Now in my opinion, a better way to store this would to be with a bracket just like this.

Now our hitch has a tab already on it to mount this, and it would mount something like this, and you'd put your connector through there and it would store like that.However, if your hitch doesn't have a tab like this, there are kits available on etrailer.com that'll set you up to be able to use this. Now something I do want to point out, is that this kit won't come with absolutely everything you need to get it 100% installed, such as the bracket which is an extra but it would be nice to have. And it also doesn't come with a self-tapping screw, which you do need to ground out the ground wire.Now many of our customers wrote in and said aside from that, this works perfectly and exceeds their expectations.let's begin our install, we're going to be working here at the back of the car, so we're going to go ahead and open up our hatch. Now we're going to open up our rear cargo door like this, and there's going to be three 10 millimeter screws that we're going to have to remove. One there, one here and one here.And once we have those out of the way, there's going to be this little center panel, and we're going to pop that out and pull up like that.

We're going to set this stuff off to the side for now.Now we're going to remove this threshold. So the first we're going to do is take a flathead screwdriver, and here in the center there's going to be a little small panel, just pop that out and then get behind this threshold and pull up. It'll be held in place with a few clips, and that's what that popping noise is, it's the clips releasing. Kind of just carefully work it.There's what those clips look like. Now underneath that threshold that we removed, there's going to be four white plastic fasteners that we're going to have to free.

Now, I'm going to use a trim panel tool, that makes it a lot easier, but you can use a flathead screwdriver too.To get those loose, you simply just go underneath the panel and pry up like that. And once those are all free, we can then grab our cargo assembly and just gently pull up on it. And what we can do, is just flip it backward just like that.Here on the driver's side, there's going to be a little panel just like this, now we're going to need to remove it. So to do that, you'll flip up your tie-down hook and there's going to be a little black plastic cover there, just take a flathead and pry up on it, and that will expose a 10 millimeter bolt underneath it.So we're going to remove this one, and then do the exact same thing for the tow hook right in front of it. Now with both of those screws out, you can take the panel and tilt it up like this, and slide it back, and set it off to the side.Now at this point, you can get your hand back in here, and find the connector that we're going to be working with. However, for video purposes, so you can see what I'm actually doing, I'm just going to remove this bracket. Let's do that. There's going to be four 10 millimeter bolts just like this.Now we can locate our connectors. They're going to be right in this area here. We're going to have two connectors that we're looking for, they're going to look just like this. One's going to be black and one's going to be white. Now, before we plug our new harness into our factory connectors, we do need to do a little prep.Now there's going to be a handful of relays that come with our wiring, and we need to plug these into our new harness. So, we're going to take two blue ones, and the blue relays are going to plug into the white ends. So you just line them up, and push them into place. And you can give it a light tug, just to make sure it's on there good.And they only go on one way, so you don't have to worry about putting them on backwards or anything like that. And then the brown relay is going to go with our brown plug. And this is something that you want to do before you actually plug this into the factory connectors, 'cause it will make life a lot easier.Now something else you can do before you completely plug it in, is put on this sticky foam. Now, you would wrap this around your relay, just like this on all three, and not only is that going to help protect it, it's going to help keep the sound down if these happen to click together.But for video purposes, we're going to pass this step. Now the kit will come with two extra blue relays, and this is going to be used for, if your vehicle does not come equipped with a factory tow package already. So to check and make sure if you need these, you're going to come underneath your hood, and behind the driver's side headlight, you're going to see a black box like this.And you're going to open this up, there's two little tabs on each side that you pull out on. And as you can see, we already have ours from the factory right here and right here. If you do not have these two blue relays, you're going to take the ones that come with the kit and plug them into place.Now these are going to install the exact same way that we put them on the harness in the back. Now we can plug our new wiring harness connectors into the factory ones. The white connector's going to go to the white, and the black will go to the black.And once again, these are only going to plug in one way. Just line them up, and push them all the way down, just like that. Now that I have everything plugged in, I just went ahead and used the zip tie that came with the kit to secure it up and out of the way.Now we're here underneath the vehicle on the passenger's side, right above our exhaust. And what we're looking for is this clip right here. Now, we're going to plug the rest of our wiring harness from our kit into that. So, now you don't have to do this, but I am just to give us a little more room. I'm actually going to pry this away from its mounting point, I'm going to pull it down a little bit.Now on the connector, there will be a dummy plug that we'll need to remove, and that just helps keep the terminals protected. So what I've found that helps, is to get a pair of needle nose pliers. We're actually going to push this tab in, and while we have it pushed in, grip the dummy plug and just pull downward like that.Now we can take the rest of our harness and plug it in. Now before we do that, I like to use some di-electric grease on the terminals, just to help keep them protected from the elements. If you need some, you can pick it up on etrailer.com. Just put a little blob of it on there, and then it simply just plugs in. Once again, it only goes in one way, just like that.Now we're going to have to ground our white wire with this pre-attached ring terminal. Now, I'm just going to use a self-tapping screw to do that, and you want to ground it to clean, solid metal. I'm just going to go right here on this bracket, but make sure you don't hit your plugs behind it.I went ahead and just ran our connector over towards the center of our hitch where it's going to be stored, and just secured the extra wiring with a couple of zip ties that came in our kit. Now before we focus on putting the inside of our interior back together, it's a good idea to test our wiring.Now I'm just going to use a tester. However, if you don't have one of these, you can just use your trailer itself. So now I'm going to hit my left turn, my right turn, my brakes and finally my running lights. Now that we've verified everything is working, we can put our interior back together.Now it goes back together the exact same way, just in the opposite order that we removed it all.And that will do it for our look at and installation of the CURT T-connector Vehicle Wiring Harness on our 2015 Nissan Pathfinder.

Works great for trailering my small sailboat and for my bike rack with my 2014 QX60. Ordered in the afternoon and it arrived the next day even on ground shipping. Took my local mechanic a couple hours to install the hitch and the Curt T-Connector Wiring. 381371

Didn’t think I could install the wiring myself using the typical kits that require splicing and tying into the battery. Then I found this kit that uses the existing factory wiring and it was the easiest install. The video provided were of tremendous help. Glad I didn’t pay someone $500 to install a hitch and wiring for me. 683444

Child’s play putter big this one on after watching the install vid.... Only thing not quite clear was the relays for the fuse box... mine only had one and something was already in it so I assume it had the towing pkg already, but I’m not sure if there was another fuse box that I should look in... there seem to be several on the pathfinder. I will never ever buy a universal and strip wires to try to make it work.... this was easy, again after watching a vid. Super simple..... 653724

Easy install thanks to the provided installation video. Check the installation video for the same product by a different manufacturer on etrailer for the location of the fuse box in engine bay 646710

Better than expected. Didn't realize my car was pre-wired for tow hitch, but it was and this kit worked perfectly. All plug and play. I do wish they would have included a self tapping screw for the ground wire though. I couldn't find a bolt to remove from the frame that would fit the already installed round end and I had to drill a small hole in the frame to mount this. Had to obtain a stainless steel self tapping screw from hardware store. Still great product though and has been working flawlessly for over a year now. 604118

  • Wiring Harness Recommendation for 2019 Nissan Pathfinder Without Tow Package
    For ease of install, the trailer wiring harness I highly recommend for your 2019 Nissan Pathfinder without the tow package is the Curt T-Connector Vehicle Wiring Harness # C56281 because it does not require any type of splicing into your Nissan's wires and does not need a direct connection run to the battery, which is often the trickiest part of a harness installation. This harness will require the installation of a couple relays (as you can see in the accompanying photo) but remains...

  • Is Complete Wiring Harness Necessary for 2017 Infinity QX60?
    I was unable to locate the comments you were referring to specifying that newer models of the Infiniti QX60 such as your 2017 would not need all of the parts, and the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56281 cannot be sold in individual parts so you would need the entire kit.

    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56281 is unfortunately not a fit for your 2013 Infinity FX35.

The correct wiring harness I recommend for you will be the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56074 which is compatible with the 2012 FX35 and the 2013 FX37 models as well as some others.

Then the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56281 will give you the trailer wiring you need. You will also need a ball mount and a hitch pin.

    The wiring harness that will fit your 2016 Infiniti QX60 depends on if you have tow package or not. If you do not have the tow package you'll need one of the universal hardwire options. I recommend the # 119190KIT. It works on a variety of vehicles, with all sorts of wiring types, and trailers with different types of lights. This will provide you with a 4-way trailer connector. If you need a 7-way you can then use our # ETBC7 kit to convert it. If your Infiniti has the factory...

    Yes, the Curt Trailer Hitch Receiver part # C13126 is a confirmed fit for a 2020 Infiniti QX60 and it offers a bolt-on installation. Furthermore, the Curt hitch has a hidden design which means you only see the receiver tube so you don't have to look at a bulky cross tube at the rear of your vehicle.
