How to Install a Trailer Wiring Harness on a 2016 Nissan Murano


Today on our 2016 Nissan Murano, we're going to be taking a look at and showing you how to install the Tekonsha T-One Vehicle Wiring Harness for 4-pole flat trailer connector, part number 118660. This is what our wiring harness looks like when it's installed. As you can see it's going to live inside the vehicle, so when not in use, you just roll it up, drop it down into your spare tire area, close your lid, and it's safely stored away. When you do want to use it, simply pull it out, drop your panel back down. What you want to do is rest it over this rubber trim here. Stay away from any connection points that your hatch is going to make.

These wiring harnesses are made to pass through your hatch area and not damage the wires. To begin our installation, what we're going to do is we need to gain access to the inside of our vehicle. The first thing we need to do is we're going to need to remove our floor coverings. We need to gain access inside here to our taillights. Next thing we're going to do is we're going to take a 10-millimeter socket and we're going to remove this panel here. Now we're going to have two mounting points.

We're going to have one here and one back here. We're going to repeat this process over here on the passenger side. Next we're going to take out our threshold and there are going to be three fasteners, so we're just going to take a flathead screwdriver, just like that. Once you have removed those, you're just going to pull up and make sure you take that out of the center so you don't break it. This should just pop right up. Next thing we're going to do is we're going to remove this holder here, flathead screwdriver right on the top side.

There's a little notch and you're just going to pull out like that. Next we're going to remove this holder here. We're going to be using a 10-millimeter socket. What we're going top do next is we're just going to take this panel and slowly pull out on it. Next thing we're going to do is locate our wiring.

That's going to be this plug here. We're just going to cut back that tape, push it down to remove it. We're going to take our T-connector with our yellow wire. We're going to plug one end into one end of the existing wiring and the other end into the other side. Now, the reason I removed the panel is for our ground wire. I'm going to try to ground to an existing bolt. I found these two here, so I think I'm going to use one of them and that's where I'm going to put my ground. I'm going to use a 10-millimeter socket. I'm going to take my white wire, the ring terminal, put it on there, replace the nut, and then I'm going to find a suitable place to mount my convertor box. Next we're going to take some rubbing alcohol and we're just going to rub the back of our box. Then we're going to rub down the spot that we're going to put it. You just want to make sure you have a clean surface. Then we're going to take our two-sided tape, put it on the back of your convertor box, peel off the other side and press it firmly into place, and make sure it's got a good hold. Next what I'm going to do is I'm going to take all my wiring, extra wiring, and I'm going to go underneath the brace here, so from here what I'm going to do, I'm just going to kind of clean up those wires and I'm going to zip tie them. Now we can put our panel back in place. Now we'll take our passenger side, which is going to be your green and your red, and we're going to feed it under this brace and then I'm just going to zip tie along this existing wiring just to hold it in place here. Next thing we're going to do is we're going to take this end, which is going to be clear, and we're going to connect it into our factory towing, so as you can see here, in between this wire, there's a fuse. We're going to go ahead and remove that fuse, so that when we connect this wire into it we don't get a short. Go ahead and plug that in, and then I'm going to zip tie my wire right here against the factory wire. Next, over here on our passenger side again, we're going to cut away the tape here for our wiring. Connect one in, the other one, and we're going to take our extra wiring, going to bundle it up, and I'm going to zip tie it to the existing wiring here. After we replace this fuse, we'll go up to the front and put our fuse in our fuse panel. Now we're going to take our 15 amp fuse, and we're going to put it per our instructions for 30 amp towing, which is going to be this one here. What we're going to do is we're going to take out this 30 amp fuse that's for the pre-wired towing package that's on the vehicle, and we're going to replace it with the 15 amp fuse for the wiring harness that we put in. Now, the reason we're doing this is because the wiring harness that we put in is only rated for a 15 amp fuse. Next we'll go ahead and replace our cover. Now we'll test it using part number I26. Brake lights, left turn, right turn, running lights. Now that we've tested everything, we know it works, we can go ahead and start putting our panels back together. Once you have this back trim piece in place, we're going to take this rubber seal and we're going to pull it on the outside edge of it. That'll do it for the Tekonsha T-One Wiring Harness for the 4-pole flat trailer connector, part number 118660 on our 2016 Nissan Murano.
