How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2016 Honda HR-V


Speaker 1: Today on our 2016 Honda HRV we're gonna be taking a look at and showing you how to install the T-one vehicle wiring harness with four-pole flat trailer connector, part number 118673. Here's what our wiring looks like when it's fully installed. When we're not using it we can store it in our spare tire compartment so it's out of the way. Then whenever we're ready to use it we can simply pull it out, drop it down the bumper out of the hatch, the only thing is you want to stay away from the latch itself. Then we can go ahead and close our hatch and we'll be ready to hook up.The end of our wiring has a four-pole flat trailer connector and it's gonna give us all the required lights to get down the road safely such as our clearance lights, turn signals, and brake lights. Now our wiring kit does come with a pre-installed and built in dust cover which is gonna be nice to help keep out some of the dirt and debris from getting inside the connector.Now that we've seen what it looks like at the end result let's show you how we get it installed.

To begin our installation we're gonna need to come to our rear hatch and open it up and we're gonna need to start removing the interior panels. If we come to the floor covering just gonna fold this up out of the way and we're gonna start working on the threshold right here. Now the easiest way to get this up is if you come from underneath towards the back of the vehicle and you just start pulling upwards it will release the clips. We're gonna go ahead and set this aside.Starting on the drivers side we're gonna need to remove or at least loosen this panel so we can gain access to the harness for our taillight right here. I'm gonna start by pulling the weather stripping away from my panels and going along down to the bottom where my panel starts at the threshold.

Now I'm gonna slowly and carefully start pulling the panel away because there are several clips holding it in place. You can see when we start pulling the panel and working our way down. Once we have most of the panel released against the side we're gonna come to the bottom and we're gonna lift up slightly because there is another clip on the bottom down here. We're gonna want to pull slightly away from this cargo hook that's at the bottom back corner and we're gonna lift up to release the clip and then slightly pull it away, just enough so that we can gain access for our harness and not damage any of the panels. We're gonna go ahead and do the same thing on the passengers side and release the panel so we can get access as well.With our panel removed on the drivers side we're gonna start with the yellow and brown wire and the connectors on that end.

Now if we follow our taillight harness it's gonna come up to this connector right here. Now this small button right here, that's gonna release the connector so we can go ahead and pull it out. We're gonna push on it, on that small tab, and carefully pull our connector apart. Now this should match the connector that's on our harness and we're gonna plug the female end into the male and the male end into the female end. We can take our harness, plug them together, making sure they lock into place.Now coming off our converter box we're gonna have a black wire that has the insulation stripped off the end.

Now we're gonna need to run this wire up to our battery and they do provide us with a length of 12 volt wire that we can run up. Now our kit does come with some butt connectors but I'm gonna be replacing them with some heat shrink butt connectors to give us a little bit of protection against corrosion. Now if you need some you can pick some up on our website. Just gonna slide it over the end of my wire that's stripped and I'm gonna crimp it in place. Give it a little tug, make sure it's secure.Now the other end I'm gonna take my charge wire that I'm gonna run up to the battery and I'm gonna put it in the other end of my butt connector and then I'm gonna crimp it in place. I'm gonna be using a heat gun to shrink down my connector. I just want to mention if you're using an open flame such as a torch or a lighter you're want to be extra careful not to char the connector or the wire itself.Now we're also gonna have a white wire with a ring terminal coming off our converter box. Now this is gonna be for the ground so we're gonna need to find a nice, clean, flat surface that we can ground our system out to. Now they do provide us with a self tapping screw and I think I'm just gonna put it right here, it's gonna be out of the way and not interfere with any of my other wiring. I can take my self tapping screw and I'm gonna screw it right into the sheet metal, you just want to be careful where you're drilling and you want to make sure that nothing is behind what you're drilling.Now we should have one more T-connector with a red and green wire connected to it and we're gonna have to run this over to the passengers side. I'm just gonna run my wire along the threshold here and I'm gonna pull my panel back and find my connector. Now the connector is gonna be in the same spot on the opposite side and we're gonna disconnect them the same way pushing in on the small tab, releasing it, and then we can unplug it. Now we're gonna go ahead and plug in our connectors the same way we did on the drivers side.Now we're gonna go ahead and find a location to mount our converter box. Now there's a couple different ways you can do it, you can use the double sided tape or there's a small tab on the top of our box and that's the way I'm gonna be mounting it with a zip tie. I'm gonna take my zip tie and I'm actually gonna mount it right here through this factory hole and secure it to the panel right here.Now as I mentioned before we are gonna have to get this charge line up to the battery of the vehicle. Now I'm gonna go ahead and pass my wire through, there's a grommet right here, to make it a little bit easier to go from the inside to the outside. I'm just gonna pull this grommet out and I'm gonna start feeding my wire through the center of it. Since there was quite a bit of grommet that goes further down and then there's a bunch of electrical tape on it I'm actually gonna cut a small slit in the grommet so that I can pass my charge line through and get through the grommet and get to the outside. We're just gonna cut from the center going outwards like that and then we can take our charge line and I'm gonna drop it down the hole and then once I can reach it I'm gonna pull the excess through.One of my wires made it through, I'm gonna go ahead and push my grommet back into place and to help seal it up since I did put that slit in it I'm actually gonna take a little bit of silicone and seal it up. Now if you don't have any or you need to pick some up you can find some silicone on our website.Everybody's gonna route their wire a little bit differently but the main thing you want to worry about is you want to stay away from any moving parts like the axles or suspension components or any heat sources like the exhaust. I'm gonna go ahead and run my wire and then I'll show you how I routed it. Here's my wire that came our of my grommet and I just followed along the frame rail here, went around my suspension, over the rear axle, and I came down, came underneath this cover, came out, went to the outside of my fuel tank, going along this brace, zip tying it along the way, and finally I have it stopping right here at the engine bay. Now let's go ahead and move up top and I'll show you how we're gonna get this wire up to the battery.I'm actually gonna take a piece of airline tube that I had laying around and you can use whatever you have. If you don't have an airline tube you can use a coat hanger or anything that's just gonna keep its structure so when we start routing it down it won't bind up. I'm gonna go behind my air filter here and start feeding it down until it reaches the bottom of the engine bay so I can meet up with my wire. Here's where my airline tube came out, I'm actually gonna take my wire and I'm gonna put it into the end of my airline tube. I'm gonna take a small bit of electrical tape so I don't have to worry about it falling out. We can go ahead and go back up top and start pulling our airline up.Now I do want to mention when you start pulling your wire up you want to double check and look underneath the vehicle and make sure it didn't get knotted up and preventing the rest of your wire to come up. You want to make sure you pull all the slack out. I went ahead and put a zip tie right here just so I could make sure that my wire's gonna be secure and not fall back down.I'm gonna go ahead and estimate about how much wire I'm gonna need to reach the positive post of my battery here and this looks like it should be plenty so I'm gonna go ahead and cut my wire right here. We can go ahead and strip back the end of our wire now. With the end stripped we're gonna take another one of our heat shrink butt connectors and I'm gonna apply it to the end of the wire.We can go ahead and take our fuse holder now that's provided in our kit. Now it is one big loop on there so I'm gonna go ahead and cut this in half and strip back both ends. Now on one end I'm gonna take it and I'm gonna apply it to the butt connector that's on my charge wire and crimp it in place. Now on the other end the kit does come with a provided ring terminal so that we can connect it to our battery. I'm gonna take the stripped end, insert it into my ring terminal, and then I can crimp it in place.Now we're gonna have to remove this nut that's holding our terminal on so we can slide the ring terminal over. Now I'm gonna be using a 12 millimeter socket to remove it. Once the nut's removed I can take my ring terminal, I'm gonna slide it over the stud, and then replace the nut. We can go ahead and put our provided 15 amp fuse in the fuse holder and now all we have left to do is start tidying up our wires and putting the panels back in place.Our wiring's gonna stay on the inside of our vehicle and we can tuck it away by our spare tire when we're not using it. Before we put it away we're gonna go ahead and test it to make sure that all our lights are working properly. Now here I've got my four-pole flat tester and if you don't have one of these you can pick one up on our website using part number I26. I'm gonna grab an extra set of hands and have them run the lights so I can verify that they're working properly. Can you turn the headlights on please Looks good. Left turn signal, looks good. Right turn signal, good. Now the brakes. Now the brakes and the turn signals please. Looks like everything is good, we're ready to hit the road.That'll finish up our look at the Tekonsha T-one vehicle wiring harness with four-pole flat trailer connector on our 2016 Honda HRV.
