How to Install a Trailer Wiring Harness on a 2008 Honda Pilot


Today on our 2008 Honda Pilot, we're going to be taking a look at and installing the Tow Ready T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, Part Number 118336. Here's what the wiring looks like once it's installed in the vehicle, and as you can see, it's very easy to keep hidden and out of the way when not in use. In order to access it, all you do is pop up this cargo cover, and there you've got access to it right there. When you're ready to use it, you simply unwind it, close you cargo cover back down, and pull it out of the rear of the vehicle here, making sure you keep it away from the latch there at the center so that it can't pinch the wires and damage them. Then leave it hang out. When you're ready to hit the road, you close your tailgate and plug in your wiring. Here's everything we're going to be working with that comes in the kit.

Our wiring harness with the wiring for the 4-pole flat connector. The connector that's going to into the factory connector that's already on the vehicle. Then the conversion box that's going to make sure all the power signals go to the right place. Over here, we've just got some hardware to help with our installation. The first thing we'll need to do is remove this little cargo cover that's back here. Pull up and we can just pop it off the hinges.

We're going to take that and just set that up out of the way, so we've got a little bit of room to work. Then the next thing we need to do is this threshold right here. We need to pop this off. It's got four push pin fasteners, two on either side. We can just get under there.

If we need to, if we can't get under there with our hands, we can use a flat head screwdriver, and it'll just pop up. You can just pop it up all the way across. Those are those fasteners. So we can set that aside as well. Right there, is the connector that we're going to be working with that we need to plug the new wiring harness into. We can leave it clipped in place there.

We just need to make sure that we have our gray connector on the harness lined up properly, and we'll push it together until we hear it click. Then we can take our little module converter box here, and because of how tight the space is here, we can just tuck it right down there. It's got some sticky pad on the back side of it. You can use that if you want but you really don't have to because it should stay in there and not really move around on you at all. We can take our 4-pole wiring and just kind of route it so that we have access to it right here. For storage, I'm just going to take the rubber band that was wrapped around it to begin with, wrap it up, and then you can leave it right there underneath your cover. Now we can reinstall our threshold and then our cargo cover. Now that we've got it all installed, let's go ahead and test it to make sure it's working. We're going to use Part Number I26 4-Pole Tester to do that. First let's check the tail lights. Then left turn sign, right turn signal, and brake lights, and everything's working properly. That's going to complete our look at the Tow Ready T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, Part Number 118336 on our 2008 Honda Pilot.
