Helpful Expert Reply:

According to Tekonsha, the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3062-P will fit your 2019 Subaru Ascent and allow you to use the Tekonsha Primus IQ Trailer Brake Controller part # TK90160. The plug is located underneath the dash and left of the steering column, taped to another harness near the emergency brake pedal which you can see in the attached photo.

Yes, you would just connect the bare wires from the Subaru harness to the pigtail wiring that's included with the Tekonsha Primus IQ # TK90160. On the controller - the red wire is for brake input, the blue wire is for brake output, the black wire is for 12V power, and the white wire is for ground.

Would this be all I need on 2019 Subaru ascent or do I need to run wires under my vehicle

As long as your Ascent has the factory tow package, the above-mentioned Primus IQ Brake Controller # TK90160 and Plug-In Adapter # 3062-P is all that you need. Everything else is already equipped from the factory.
