I’ve been considering a hitch for our 2021 Model Y, but exclusively so we can haul two kids’ bikes, along with an adult hybrid/fitness bike. I know I can get the OEM hitch from Tesla for $1,200+tax, but I am also considering less expensive options, such as the Ecohitch and the Draw-Tite 76430 (I’m also open to other suggestions).

As I understand it, the wiring harness is only necessary if I plan to tow a trailer, which I do not ever plan to do. If my understanding is correct, would I be okay foregoing the wiring harness, which adds another $100-$250 in parts and labor? Any drawbacks to not having the wiring harness/kit?
