I would check both idatalink.com and fortin.ca for your vehicle. Download the install guides and they will contain some (possibly all) of the wiring information you need. Since vehicle interfaces handle many of the vehicle functions now, if you use one, it can simplify your wiring.

Also, here's a link to your vehicle's factory wiring diagrams: https://cardiagn.com/toyota-2016-2022-prius-electrical-wiring-diagram-em3200u/
