How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2006 Honda Ridgeline

Today on our 2006 Honda Ridgeline, we're gonna be installing Tekonsha's T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector. This vehicle wiring harness is gonna provide you with all the necessary lighting you need for your trailer. This includes your left turn signal, right turn signal, tail lamps and brake lamps. It's an easy installation. It simply plugs directly into your factory connectors between both your passenger and driver's side taillights. So there's no cutting or splicing involved.What's nice about this harness is the control module that's included with it.

So this way if you have a fault on your trailer, it won't affect the lighting that's on your vehicle. The module acts as a buffer in between the two. Our 4-pole connector here on the end has a dust cap that is pre-made onto the connector. This can be put on to keep out any dirt, debris and moisture to ensure you have a long lasting connection. You can also loop it through your safety chain loops and this'll keep your connector up off of the ground and out of the way.We'll begin our installation at the back of the vehicle with the tailgate open.

We're gonna need to remove both the passenger and driver's side taillights. You'll see two bolts located here on the inside. We're gonna remove those with a 10 millimeter socket. Then you can just pull your taillight assembly rearward and that'll pop it out and here on the inside, we're gonna need to find our electrical connector right here. We'll disconnect the connector and set out taillight aside.

We'll do this exact same procedure on the other side.We can now take our wiring harness. We're gonna use the yellow and brown circuits that are coming off of it and this is gonna plug inline between our tail lamp assembly and our factory connector here. So we're gonna go ahead and plug in the factory connector side. We'll save this for later. This'll plug back into our taillight.

Now we're gonna need to install our ground wire. So we're gonna put that about right here. We're gonna use the self tapping screw that comes included with our kit, put it through the ring terminal at the end of that white wire. Now we'll use a quarter inch socket to thread that into the metal behind our tail lighting.We'll now take our module. We're gonna stick the adhesive backing on it. So we'll peel off our cover there, stick it to the back of our module. Next we'll stick our module onto our vehicle. We're gonna place it down below here. So I've already taken a cloth with some alcohol on it and cleaned that up just to ensure we'd have good adhesion. We'll peel off our other backing. I'm going to stick the module right below the opening there and you just wanna keep it pressed up against that wall there for about 25 seconds.We'll now pull our wiring down. We'll now need to run our wiring across to the other side. We're gonna do this with both of our connectors here except our 4-pole, we're gonna stop about halfway. So we're gonna go ahead and just push that one in. That's gonna stop about there. This one's gonna continue all the way to the other side. Now that we've got our wiring fed over to our passenger's side, to get this up here, I just reach my hand down there and pulled it out. There's plenty of room for your arm to get in there. We'll now plug our wiring into our factory connector here just like we did on the driver's side and our passenger's side taillight's gonna plug right here into this connector here.We can now reinstall our taillight assemblies. So we're gonna plug those into the other side of our harness connector. I'm just gonna take that wiring and push that down in there. We can then put our bolts back in and tighten 'em down. To verify everything's working, you can plug in a tester like the one we have here that you can pick up at or you could just plug in your trailer. You wanna make sure that you have your left turn signal, right turn signal, tail lamps, and brake lamps. And with everything working properly, we're ready to hit the road.And that completes our installation of Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector on our 2006 Honda Ridgeline.
