Question:
Hello I am looking for a trailer wiring harness for my 2018 Subaru outback 2.5i premium. Without the tow package. There is no plug in the rear panels. Do you have a plug in option for me rather then the universal splicing option ?

Hello Patrick,
Looks like you already found it. For your 2018 Subaru Outback Wagon the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector # HM11143885 is a plug-n-play option. Even though your Outback 2.5i did not come with the factory tow package, it will still have the plug in for # HM11143885. Don't forget to grab a Mounting Bracket 4-Pole Flat # 18144 for a nice clean looking install. I also included an install video for the wiring installation, looks like all the work is just getting to the connector to plug it into.
What do you plan on using the wiring for? I am happy to get some other part numbers together for you.

Hey Patrick, how did things go with the Hopkins plug-in wiring harness on your Outback? Did the connector end up being easy to reach behind the panels? Your update could make it easier for others working on the same setup.
