How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2017 Nissan Murano

How's it going Ryan here at Today, on our 2017 Nissan Murano, we're gonna be taking a look at and showing you how to install the Tekonsha T-One vehicle wiring harness. Many of our Murano customers use their SUVs to do a little bit of everything, and that's going to include towing and that's where you would use this trailer wiring. It's going to provide us with the necessary lighting functions. That way, the trailer lights match the back of our Nissan lights and we'll be safe and legal. And we're also gonna have a really nice, thick rubber dust cap, which is going to help keep your terminals protected from any rust or corrosion.

And what you can also do, say, for example, you drop your trailer and you plan on picking it up later, you can actually just keep it stored on the side by wrapping it around your safety chain loop. That way, you don't have to loop it up, bring it back inside. You can just keep it like this for the time being until you go to hook up to your trailer again. And it's also going to give us plenty of length. That way, we shouldn't have any issues when we go to hook up to our trailer.

Now, one thing I really do like is the fact that our wiring is going to use a module box, and that module box is going to protect our factory wiring if a short or an electrical issue we're to occur on our trailer side. Whenever we're ready to use it, it's really easy. Just lift up our storage compartment, grab our wiring and drape it over our threshold here. Now, anywhere along the threshold that has this weather stripping is going to be fine. You just wanna make sure to avoid the latch area here.

That way, we don't have to worry about our wiring getting damaged. Then whenever you're done, simply just bundle it up, open your compartment, and keep it stored inside, out of the weather and out of sight. Now, this is one of the easier wirings to get installed, and shouldn't take you a whole lot of time. Speaking of which, let's go ahead and hook it up together now. To begin our install, we're gonna be working here in the back of the Murano, so we'll need to open up our hatch.

We're gonna remove these side panels. So, we'll have one on each side, and these just pull up and out of the way. We can lift up the center section. And ours has a little hook here underneath it, so we'll just use that to kind of loop it around that latch and keep it up like this. Now, on the driver's side, we're gonna remove this compartment. It's gonna be held in place by two 10 millimeter fasteners. Just pull those out with a socket. Once those are completely loose, you can kind of grab it. Just work it around till we get it free, then set it off to the side. On the passenger side, we're gonna have that same setup with the exception of one thing and that is we're gonna have to take our tire jack out. So, once that's out of the way, it'll let us get access to those two 10 millimeter bolts. Now, on the driver's side, we need to locate our plug and that's going to be this white plug right here taped to this wire loom. So, to get us a little more room to work, I'm just gonna take a knife and just kind of trim that tape back to allow us to pull that plug off. Now, to get it disconnected, we're gonna have a tab here in the center, push down on it and separate the two. Now, what we're gonna do with that is take our new wiring. We're gonna take the T-connector end that has the yellow and brown wires, and we're just gonna tap into that. So, one connector will plug on the one side, and the other one will just simply go into the other end. So now, we need to find the factory connector that plugs right into our new wiring power wire here. Well, that factory connector is going to be located right here. And again, it will be taped to some wiring. We can kind of just pull that out like so. Then we just simply plug the two together. Now, we're gonna take our T-connector end that has the red and green wires, and I'm just gonna run this right over to the passenger side because this will just plug right in just like the driver's side. So, right here is where the connector is going to be located. And I went ahead and just cut that tape off just like the other side. Just push that center tab down to separate the two. And again, one end of our T-connector will plug into it. The other end to the other side of the factory connector. Now, we can take our white wire with the pre-attached ring terminal that comes out of our module box and ground that to our chassis. So, we want to pick a clean, flat spot of metal that we're gonna get a good bite on. So, I'm gonna put it right here on this thick bracket. I'm gonna do that using the included self-tapping screw. Now, we're underneath the hood right here on the driver's side. We need to take off our fuse box cover to see if there's a fuse in place. So, to do that, we're gonna have a couple of tabs right here and here. Gonna pull up on them. We're able to pull it up and lift it out of the way. Now, if you look on the back of the cover, we're gonna have a diagram here that indicates what each fuse does. Well, the fuse that we're looking for is this one right here that'll be labeled towing. If you look here in the fuse box, this is the spot that we're looking for. Now, our vehicle already happens to have a fuse in place, and if yours does as well, that's all you need to do. Just put your cover back on and go on to the next step. However, if yours does not have a fuse in place, all you'd simply do is take the provided fuse with the wiring kit, insert it, put your cover on, and then move on to the next step. To get the cover back on, you simply just line it back up and push it down. Now, before we secure all of our wiring and tidy everything up, it's a good idea to check everything to make sure it's working properly. So, I'm using a tester, which you can find here at, or you can simply just plug into your trailer. But with that being said, we'll try our left turn, our right turn, our running lights, and our brake lights. Now, since we verified everything is working properly, I went ahead and secured our wiring and our box using some zip ties. Now, as far as the red and green wire goes, what you can do is just kind of bring it behind this threshold panel here. Just kind of tuck it up. We can kind of pull that slack out of it and secure it to a wire with a zip tie to keep it nice and tight and out of the way. And this is what the other side looks like when it's fully secured. Now, at this point we can reinstall all of our interior pieces in the opposite order that we removed them. While putting this compartment in, you wanna make sure to run your four-pole wiring through this little opening here where our factory wiring runs. That way, we can store it in our truck and easily get to it. And that'll finish up our look at and our installation of the Tekonsha T-One vehicle wiring harness on our 2017 Nissan Murano..
