Question:

Hi, I am needing a full towing package for a 2019 Subaru Ascent Touring. I would need a Class 3 hitch plate, a trailer brake controller, and a full wiring harness with a 7 blade connector to pull a travel trailer. Would you be able to send me some options and pricing for that full kit? Thank you!

Hey Zach, I'd be more than happy to help you get your 2019 Subaru Ascent set up for towing a trailer!

Here are the parts I recommend using:

- etrailer Trailer Hitch Receiver # e55ZR
- T-One Vehicle Wiring Harness # 118790
- Universal Installation Kit # ETBC7
- Curt Echo Under-Dash Bluetooth Brake Controller # C47YV

I really like the etrailer hitch because it has a matte black finish that lasts better than a glossy finish, and then the T-One wiring is the most reliable, and the universal kit is needed in order to install a brake controller. As for the Curt Echo, since it sits under your dash and you control it with an app, it really frees up your dash and keeps it looking really clean.

Do you already have a ball mount to tow the trailer?

Hey Zach, did you have a chance to set up your Subaru Ascent with the towing package I recommended? I'd love to hear how it worked out for you, as it could help others looking to tow with their Ascent!

@JonG yes! Everything worked great. Hitch mounted to the frame with little effort and the electronics were plug and play. The only other thing I would recommend buying is a push pin puller. Thanks for the help!
