The Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR you were looking at will absolutely work in your 2021 Subaru Ascent, but how it is installed will depend on if your Ascent has the factory tow package or not.

If your Ascent has the factory tow package you will be able to use the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # 3062-P which will plug into the factory trailer brake controller port underneath the dash of your vehicle, and will only require you to physically mount the controller to complete the installation.

If your Ascent does NOT have the factory tow package you will need to install a 7-way connector using the Tekonsha OEM Replacement Vehicle Wiring Harness with 7-Way Trailer Connector # 118290.

You will then need to hardwire the # RED44FR making the following connections:

Black wire to vehicle battery with 20 amp circuit breaker if trailer has 1-2 braking axles, or 30 amp circuit breaker if trailer has 3-4 braking axles
White wire to ground
Blue wire to blue wire of # 118290
Red wire to cold side of stop light switch that only has power when brakes are applied. You will need a circuit tester like # PTW2993 to find this wire.

If your vehicle has the factory tow package the installation is very easy and you can absolutely do it yourself, but if you do not have the factory tow package and are not comfortable with vehicle wiring you may want to have a local automotive repair shop complete the installation for you.

I included videos of the products mentioned for you to take a look at.
