For us eager beavers waiting to take delivery of their Model 3 in CA and wanting to install the Tesla HPWC, before delving into the detailed High Power Wall Connector (HPWC) installation manual, this installation video from Tesla may be all one needs: Installation - TESLA Wall Connector
That's awesome!... I can't wait to pick up my connector and then get it installed!... I love how Tesla makes even a charger look beautiful and futuristic.
I shoulda watched that first - I quickly skimmed the manual and then bought the security Torx bits as part of a $15 kit at HD. I opened up that kit and threw out the packaging before the rest of the HPWC hardware pack and voila - Tesla was smart enough to send the Torx bits. Don't make my $15 mistake.
