Why Does Trailer Wiring for 2004 Honda Pilot Route Through Back Door

Question:

I recently purchased a Tekonsha 118336 for my 2004 Honda Pilot. All of your videos show to run this under the back hatch. The existing wire that Im replacing is run through the bottom of the vehicle through a couple of built in access holes. Why dont you run through these in your videos? Do you know where I can get the seals that fill the hole and protect the wires?

Having the 4-way run out of the back hatch is actually the preferred method although it seems like it wouldn't be. Having the 4-way stored inside the cab of the vehicle keeps it protected from rain and moisture to prevent corrosion and keeps it protected from damage to the wiring or connector by rocks or debris that might be on the highway.

You can run the wire through the vehicle if you wish but just keep in mind that this does take more time and you may end up needing additional wire because you will not be routing the wire in a straight line.

As far as mounting the 4-Way end under the vehicle, that, too, can be accomplished though there is some extra work involved and you may have to drill through the bottom of the vehicle. You would need to remove as much flooring as you can from the cargo area in the van, getting down to the bare metal. At this point you would need to locate a grommet or other opening through which you can route the wiring. However there is a good chance any grommet you find will not be large enough to accept the 4-Way.
