Hello David,
You are correct (3 words everyone likes to hear) the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56367 will only work with the wagon.
For your 2017 Subaru Impreza Sedan you will want the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56212. You were not able to find it by going through our fitguide because it is currently on an extended back order, looks like you wouldn't be able to get it until early to mid September.
If you are needing the wiring before then, you will need to go with a splice in application. The Curt 4-Way Flat Trailer Connector with Circuit Protected Powered Tail Light Converter # C56496 will work great, it's just a little more work to install.
What are you planning on using the wiring for? Do you have the other components that you need?
BTW- etrailer is lucky to have you as a customer =)

Hey David, Did you decide to go with the splice-in option for your Subaru Impreza Sedan, or are you waiting for the back-ordered harness? I'm curious to know how it worked out for you because it could help others in a similar situation.
