“Not easily, as requires wire harness changes“ Elon Musk on TwitterI can't find the tweet at the moment, but this is correct. I believe it was something like the wire harness is different and it would be quite a process to retrofit.
And even if you somehow found a way around that wire harness issue you’d still need to edit the gateway config to tell the car it has one. You’d need service to agree to do that unless you somehow manage to get root access to the car.
