Pretty sure that center console just pops off and they plug in the usb-c’s to the respective source, connect to the housing and then pop it back on. Everything in these cars seems very simple to pop off and on. Should be pretty easy access too with the ’brain’ right there under the dash.There have been reports on Reddit and other Tesla sites thst mobile service was able to do the work too. So it must not be complex or too long to do.
