I believe they are supposed to contact buyers a week or two before Lightning delivery, to deliver or schedule installation of the charger so it could match up with the truck delivery. Either way my solar company is doing the install and is running the wiring so when my Lightning is here they can hang the charger and be done. I believe there is a pdf out there for those that aren’t using SunRun for their installation or the home integration. Works fine for me since I already have solar and battery backup and the ev charger install is included in my solar/battery install.
