Installing a 7-way Trailer Connector on a 2018 Subaru Outback


Do you have a 7 blade tailor wiring kit for a 2018 Subaru Outback?

We do have what you need to add a 7-way trailer connector to your 2018 Subaru Outback Wagon but there isn't a specific custom harness that fits.

If right now the Outback has no trailer wiring at all the easiest way to add a 7-way is to start with a plug and play 4-way and then convert it. I recommend using the Tekonsha, part # 118467, for the 4-way. It plugs in to a connector that's either behind a trim panel in the rear cargo area on the driver's side or in the spare tire compartment. I've linked a video of an install for you.

Once you have a 4-way connector, or if you already have a 4-way connector, use our # ETBC7 kit to convert it to a 7-way. The kit includes the 7-way connector and all the wiring you need to make it fully active. It plugs into the 4-way you have and then the 12 volt power wire is run to your Outback's battery, the reverse light wire splices into its reverse lights, and the brake circuit is ran in the cab of the vehicle to connect to an electric brake controller. Everything you need is included except for the brake controller itself. I've linked a video of this install as well. It's on a 2011 Outback but the kit is universal so the process is very similar.

The video of the # ETBC7 install also shows the Prodigy P3 brake controller, part # 90195. If your trailer has electric brakes and you need a controller this is definitely the one I recommend. It's easier to install and use than most because it can be mounted at any vertical angle and the LCD makes reading the screen a lot better.
