Hello Stephen,

Welcome to etrailer! I'm glad you found us.

Yes, the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C98RJ is a great fit for your 2024 BMW X3 M40i.

If you're also looking for a hitch, the Stealth Hitches Hidden Rack Receiver - Custom Fit - 2" # SH46FR is the only hitch we carry that fits the M40i. It comes with a removable 2" receiver that's designed for hitch-mounted accessories like bike racks and cargo carriers. Installation does require temporarily removing the rear bumper fascia, and you'll need to trim the gravel shield under the rear of the vehicle, but there is no drilling required into the vehicle's frame. The nice thing is when you remove the receiver, you don't even know you have a hitch installed.

If you plan on towing, you'll also need the Ball Mount for Stealth Hitches Hidden Receiver Hitch # 391BMU5S along with the 2" Hitch Ball # 40038.

What do you plan on using the wiring for, light towing, or hitch mounted accessory?
