Hey Tim, this thread discusses wiring the OEM fog lights:
2020 SR+ Foglights
It's a pretty easy process that involves splicing two wires together. A few youtube videos do a pretty good job showing how it's done. You won't be able to turn the fog lights off and on because the car doesn't come with it programmed onto the screen, but they'll turn on whenever the accent bar light comes on. With that said, I took it to a local shop that specializes in Tesla's and they installed it pretty quickly.
