Next, we'll install a 7. Now for this application, theres a manufacturers ground located next to the threshold behind the quarter panel. To remove the rear threshold, we'll first need to remove the two tie-down fasteners, one located on each side. Next we'll move to the back of our quarter panel that we removed earlier, and take the white wire with the pre-attached ring terminal which will be the ground for a new wiring harness, and ground it to the vehicle body. The brown wire terminal will be our running light circuit, yellow wire terminal will be the left turn signal, left break, and green wire terminal will be the right turn signal, right break. We'll be using the manufacturer port here. We'll go ahead and remove the ground stud, put it over the white wire ring terminal, and then reinstall the ground stud back in the manufacturers position.
Then, using an interior trim panel tool or a flat-blade screw driver, we'll get underneath the threshold and release the fasteners underneath, as we pull out and up on the rear threshold. On the drivers side, we need to remove the cargo hook at the top of the interior quarter panel. The white connectors will come out through the excess panel hole where we removed the cover earlier. Is there an easier way to finish this by myself? This is what I did. I didn't need to go into the first cubby hole on the left side of the cargo space, like some threads advised, everything is in the little aux fuse panel on the right side of the big cubby hole panel. Then we'll remove the rear threshold. Hi Piloteers, I recently purchased a 2014 Pilot with factory trailer hitch and found that the wiring only goes so far.
I find it so stupid that Honda would only go so far with the wiring, but also understand that it was done because there are a few different kinds of plugs you could end up with. Any help would be appreciated. Note, be careful to stay away from the vehicle cargo door latch as pinching it in the latch can harm the wire. I of course bought the wrong bracket but I was just going to use it as a back brace anyway so a workshop vise and a drill solved the mismatched holes issue. With the quarter panel and threshold reinstalled, we'll now go ahead and reinstall the fuses into the fuse box for our new wiring harness.
I also bought a mounting bracket but you don't need it unless you are going to mount the connector behind the bumper instead of on the bumper. To begin our install we'll first need to go ahead and open up the rear cargo door. The instructions from etrailer were pretty simple, the only place I got stuck was where to connect the two relays I had to back track to figure where the relays went when I realized I had parts left over when I was done. Now with the wiring harness grounded, we'll go ahead and take the grey connector of the wiring harness and plug it into the converter box. . We'll be able to take our new wiring harness and feed it behind the quarter panel, between the two interior quarter panel pockets. That does it for the install of the Tow-ready, T1 Vehicle Wiring Harness with four-pole flat connector, part number 118521 on our 2014 Honda Odyssey.
Then we'll pull out the necessary wire to run to our hitch accessory, and we're ready to hit the road. However, the weather stripping is thick enough that it won't harm the wire and we can simply close the rear cargo door on it. Next we'll remove the access door located behind the third row seating here on the drivers side. We'll go ahead and pull out on the quarter panel and release the fasteners underneath just like we did the threshold. Now with that done, the four-pole harness will simply run down and underneath the interior paneling, and we can go ahead and reinstall it. However, for this application theres nothing in the port so we can plug directly into it and feed the other end of the T connector out of the way.
Now with all our fuses installed, we're ready to go ahead and test our new four-pole wiring harness. If theres already an electrical connection point in this port, we'll remove it first, then plug our harness into the manufacturers fuse box, plugging the other end of the wiring that we removed from the fuse box, into the other end of our T connector. Now once we've released the fasteners underneath, we can go ahead and remove the threshold and set it aside for reinstallation later. To secure the converter box, by removing the two-way adhesive, looking for a clean flat surface to adhere it to, and then putting the converter box into position. Now we know our four-pole harness works so lets go ahead and show you how to use it. Can I go to an Auto store and buy a plug that connects to the one under the Pilot and have it come out by the rear bumper without going to or through the fuse box? Simply open up the rear cargo door, take the four-pole harness, run it towards the center of the vehicle and down to the hitch. Using a test light, we can simply go ahead and remove the four-pole harness cover and put the ground clamp over our test light, over the white wire terminal.
Starting with the 10F fuse, we'll plug it into the number 8 position as per the diagram on the back of the fuse panel cover. I hope this makes sense, It really only took me about a half hour.
