How to Install a Trailer Wiring Harness on a 2013 Honda Odyssey

Today on our 2013 Honda Odyssey, we'll be installing the Toe-ready T1 connector, part number 118521. To begin our install we'll first go ahead and pull the latch for the drivers side rear third row seat and lean it forward, so we can gain access to the rear fuse panel. Then using a flat-blade screw driver we'll go ahead and get underneath the fuse panel, and remove the fuse panel door. Go ahead and set that aside. We can remove the rear threshold. To remove the rear threshold, we'll first remove the cargo hooks or knobs. Next we'll need to remove the rear cargo liner.

Then we'll get underneath the rear threshold, and gently pull up releasing the fasteners underneath. Now we'll go ahead and set the rear threshold aside. We'll need to gain access behind the drivers side interior side panel. We'll go ahead and remove the top cargo hook.Now we can pull back on the interior panel a little further gaining easier access to where we can actually put our hand and arm up behind the interior panel. Now we'll go ahead and take the T1 connector and the 12 pin connector, and plug it into the back of the fuse panel, running it up behind the interior trim panel.

Here we'll remove the ground bolt, take the white wire with the pre-attached ring terminal, install the ring terminal onto the bolt and then rescuer the bolt to the vehicle. We'll take the gray plug from our toe-ready harness and connect the converter box. Next we'll need to adhere the converter box to the vehicle. To do this we'll remove the two-way adhesive and attach it to the sheet metal, in that inner pocket area. Now we'll make sure our four-pole wires run out into the rear cargo area, and we can go ahead and reinstall the interior trim panel. Next we'll need to install three fuses supplied with the install kit.

The 10 amp fuse in position number eight, and a 7.5 amp fuse in position two and eleven. Quick tick 00:03:00 tip, I recommend to take a blank zip-tie, and secure the four-pole connector to the manufactures wiring as it routes out in the rear cargo area. We can go ahead and reinstall the fuse panel cover and the drivers side interior trim panel. Then we can reinstall the rear threshold, and our cargo liner, putting our seat back into the upright position. Next we'll go ahead and show you how to use the new four-pole connector. We'll simply take it out of the rear cargo pocket, and run it out and down to the hitch or accessory. Be mindful to stay away from the latch, as pinching the wire off in the latch can harm it, however the weather stripping is thick enough that it won't hurt it.

We'll simply close the rear cargo door on it, and then pull out the necessary wire to run it down to our hitch or accessory. Then once we're finished using our new four-pole connector, we'll simply reinstall the four-pole cap, roll it up storing it inside the vehicle. That does it for the install of our new toe-ready T1 connector, part number 118521 on our 2013 Honda Odyssey. .
