Question:
I currently see two wiring harness kits listed for the 2025Volvo XC60 Plus, T8 (PHEV): the C84RJ and the C59236. Which one should I order? Are there any real differences between them? I will be towing a boat and trailer (no trailer brakes) totaling 3000 pounds as well as occasionally mounting a bike rack on the Curt C92WR hitch receiver.

Unless you enjoy cutting and splicing wires, I strongly recommend going with the Curt T-Connector Vehicle Wiring Harness item # C84RJ over the item # C59236. The Curt item # C84RJ is custom-fit and plugs into your Volvo's wiring harness in your rear cargo area. The Curt item # C59236 is a universal harness that splices in manual to the tail light wiring.
The Curt Hitch item # C92WR, you referenced, is confirmed to fit the 2025 Volvo XC60 Plus. It is a class III hitch with a 2" receiver that has a 4,000 lbs towing capacity and a maximum tongue weight of 400 lbs. This hitch will be perfect for both your boat and hauling bikes.
To round out your towing setup, I also recommend the Curt Towing Starter Kit for 2" Hitches item # C45534. This towing kit will provide you with a 2" ball and a fixed ball mount with a 3/4" rise and 2" drop. It also includes a hitch pin and clip, hitch receiver lock with keys, hitch cover, and a storage case.
Does your boat trailer not have any type of brakes or do you just not need a brake controller because they're surge brakes?

Thanks Jerred. At a combined weight of 2990#, it has no brakes. I've ordered the hitch and T-connect wireing kit. The unfortunate news the harness kit is on back order. I'll wait for the convenience.
