How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2022 Honda Odyssey


Hey everybody, how's it going Today, we're gonna be going over and showing you how to install the Tekonsha T-One Trailer Wiring Harness here on our 2022 Honda Odyssey. So this is what our trailer wiring harness looks like installed. So when we need to use it, we are gonna be draping it out of the hatch here. So we can easily just plug in our trailer connector. And I know this doesn't necessarily look the best driving down the road, but it's the most ideal for this setup here, because when we're not using it, you can see here it's gonna be stored inside the vehicle. Now, the reason this is important is chances are we're not gonna be towing everyday.

Therefore, having our trailer connector stored inside the vehicle here, it's gonna keep it nice and safe. Make sure we don't have any issues with rust and corrosion due to water that can affect the functionality of our tail lights. So then when we are ready to use it, it's just as simple as taking it out of our storage compartment there and then draping it out the hatch here. It's actually gonna close here on this weather seal. So we don't have to worry about it damaging our wire.

You can see here, we still have a nice lead. We can still attach our trailer too. So a trailer wiring harness is gonna be one of the few components that are gonna be required to successfully tow a trailer. Now, the wiring harness essentially transmits the signals from our vehicle here to the trailer. So we can let other motorists out on the road and know what we're doing.

A lot of the times our trailer is actually gonna be blocking our tail lights here. So we need a way to let others behind us know what signals we're gonna be making. So we can arrive at our destination safe and sound. So in regards to install, this particular kit plugs into a factory tow package port, which all of our minivans here are gonna have. You don't have to worry about checking with the manufacturer whether or not you have a tow package.

Every single one is gonna have the plug that's gonna make for an extremely simple installation. We actually don't have to modify the vehicle at all. There's no splicing. There's no drilling. Everything is plug and play. So with the tow package plug here, one thing that we're not gonna have to worry about is any issues on our trailer affecting the lights on our vehicle or vice versa. Everything is gonna be independent on their own separate circuits. So we don't ever have to worry about losing the tail light functionality here of our van. Very simple, definitely something I recommend you guys trying at home. We should really only need minor tools to get this done. And we'll walk you through this entire process, step by step now. So now the first step of our installation, we need to open up the hatch on our vehicle here, come over to the driver's side. We're gonna have a removable panel here. There's gonna be a little indentation at the bottom there. We can get our fingers in there and just pull out like so. Now directly behind this panel here, you're gonna see part of our wiring harness. And then sorta tucked behind there, you should see a blue connector. Try to fish that out for you guys now and that's what that looks like. So if you wanna give yourselves a little more into work, you can actually just cut that tape there that was attaching it to the other wiring harness, just to give you a little bit more a longer lead, but now we're gonna take the wiring harness that has our kit here, and we're gonna find the matching blue connector there. We're just gonna simply attach it to the one on our vehicle, just like so until it clicks into place. Now, the next thing we're gonna do is we're gonna take the interior that has our trailer connector on it. So this is our 4-pole end. We're gonna be taking this. We're gonna be routing it behind the panel here next to the fuse box, like so. And then I'm gonna pull up on this panel here 'cause I'm gonna try to fish it out up underneath. So, now that we've got our connector here, we just pulled back on this panel. Give us a little bit more room to work. We're gonna take all this excess here and we're gonna pull that through as well. So the way this kit is designed, our 4-pole trailer connector here is actually gonna be stored in the vehicle. I actually recommend that for most infrequent towing, unless you're towing everyday, storing this inside the vehicle is gonna keep it nice and safe. If we wanted to, we could peel up all this carpet here, find a grommet underneath here, poke a hole through that, then we can route our trailer connector to the outside of the vehicle. But again, I really only recommend that if you're gonna be towing everyday. It makes things a little bit easier, but for the majority of applications, storing it inside the vehicle is gonna keep it nice and protected and in full functioning order. So the next thing we're gonna be doing is we're gonna take this white wire here, coming from the converter box with the ring terminal pre-attached. This is our ground wire. Now we have a couple of different options to attach this. If we want, we can use the self-tapping screw that comes in your kit, just drill into that metal bracket there and secure it like so. If you don't wanna do any drilling, it's kinda hard to see, but back between the fuse box here on that same metal bracket, there's actually a weld nut on there that we can utilize if we pick up an M6 by one inch screw, like so. So if you have one of these, the spare one, or you wanna head to the hardware store, pick one up, we can install this without drilling. So I will say, this is kinda hard to reach back there. So you can see that we have a socket and a little leader just to give us a little bit more room here. But I'm gonna stick the ring terminal over the bolt, and then I'm going to stick both of those back there. Try to line it up with that factory weld nut as best as possible and get our bolts started. There we go. So there we have it there. Again, it's pretty hard to see, but with the right tools there and that extra bolt, we can avoid drilling into the vehicle here and our ground wire is nice and secure. Now, the next thing we're gonna do is we're gonna take our converter box here, along with the included double-sided tape that comes in your kit, gonna stick that on the back of there. And then we're gonna find a nice flat level surface to attach to this to. So now that we have our converter box stuck to that metal bracket tucked back there, we're gonna take our blue 15 amp fuse, and we're gonna insert it into the inline fuse holder here on our harness. Go ahead and cover that up. And I'm gonna take all this extra wire in our connectors. I'm just gonna shove that down there in that open space that we have, just like so. Now you've got a couple of fuses to install. We're gonna start with the pink 30 amp one here. And if you remember the panel that removed earlier here, on the back side of that is gonna be our fuse diagram. So we're gonna be installing this pink fuse here into the number 12 spot, which is located right there. Next we have our 7-1/2 amp orange/brown fuses. Those are gonna install into the number 10 and 11 locations, which are right down there. Now with those installed, we're ready to test everything out. Now, at etrailer, we like to use this little 4-pole plug-in testers because they help isolate any issues we may have, but you could obviously use your trailer as well. There's no connector to the problem with the trailer, it's gonna carry over to our testing with the vehicle, making things a little bit more difficult. Now that we have our tester hooked up, we can go ahead and step on our brakes here. You can see we have both lights for our brakes, our left turn, our right turn, and then finally, our tail lights. So, there we go. Now we know everything hooked up and working correctly. So now that we're done testing here, we're simply gonna take the rest of our trailer connector and our wiring harness. I'm just gonna coil it up and I'm gonna store it here in this pocket. And that's gonna do it today for our look and installation of the Tekonsha T-One Trailer Wiring Harness here on our 2022 Honda Odyssey..
