How to Install a Trailer Wiring Harness on a 2010 Honda Odyssey

Today on this 2010 Honda Odyssey, we are going to install part number 118438 from Tow Ready. The first thing we need to do is get to the rear of the vehicle. We are going to open up the back hatch. And the first thing that we need to do is remove the rear threshold right here. We will start off by removing the tie-down anchor points right here. And they just unscrew. Alright, and there is a series of clips on the top right here. We will go ahead and undo those. And there are some on the backside here we can simply just pull out with our fingers. Alright, now we are going to do the same thing with this panel here, but we are not going to take it all of the way off. We are just going to loosen it up so we can get behind it. We have one more anchor point that we need to remover here too. We are going to take our lid off of our jack storage compartment and we are going to pop it loose too. And we just need to move just that little bit. That is all we need. 1:07

Alright, getting back to our passenger side of the vehicle, we will show you where the port is for you to plug in the t-one connector. Alright, we are looking at the junction box here. It is in the top right hand corner. We are looking at it, basically facing out the back of the vehicle. We will take our t-connector and we are just going to plug it right into the socket here. Find a nice place for the module. We are just probably going to stick it back here somewhere. Then we are going to take our white ground wire and we are going to attach it to this ground right here. Alright, we will go ahead and leave that alone now. We are going to run our 4-pole wire here, along the factory harness back over to the other side. We are going to slip it underneath the plastic and hide it inside the jack storage compartment. Alright, once we have that accomplished, we will go ahead and just zip-tie the wires to secure everything together. At this point, we can go ahead and start popping the interior panels back together. 2:18

With that, our install is basically complete. We will go ahead and show you how to use it now. First off, when you are not using it, this whole wire harness will stay inside the jack storage compartment. And everything will be hidden out of the way. And when you need to use it, just go ahead and pull out a little bit of the length, go ahead and set it down here. The door shield is plenty thick it will not hurt anything if you shut the door on it. Just make sure that you stay away from the latch though. OK, we shut the hatch. Now we can go ahead and just pull out what we need to reach down to our hitch. We are done with the wiring harness out back. Let us go up to the front of the vehicle where the fuse panel is. And it is going to be on the passenger side of the vehicle. You just want to go ahead and just pull out this lid. This slot right here is where our fuse will go. Alright, now that we have our fuse in the panel, let us go ahead back to the 4-pole and test to make sure everything works. 3:10

We will test our 4-pole by taking our ground clamp and connecting it to the white wire. Then we will test our running light first, that will be the brown wire. OK, then we will try our left turn which will be the yellow wire and then right turn, which will be green. And now test our brake signal, which will be the yellow and green wire. OK, with that it looks like our test works just fine. And that will finish our install for part number 118438 from Tow Ready on our 2010 Honda Odyssey.
