Why Does Trailer Wiring for 2007 Subaru Forester Route Through Trunk

Question:

Is there the possibility of slicing one of the trunk pan grommets and threading the wiring down through it? Then resealing with silicone or hot glue to prevent exhaust from entering the cabin or is the trunk door access the only option for the forester? Signed the Mountain Bluebirds owner

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 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 vehicle, 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.
