The ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT will be the best option for a no-splice wiring harness for your 2021 Tesla Model Y. The kit will completely bypass the factory wiring. It uses sensors that clamp on to the factory wiring and detect electrical current, so no cutting or splicing will be needed.

I have linked our install video below if you want to take a closer look.
