I am still in planning stage and already done with 2 rounds to HomeDepot. I have decided not to start without VIN. My installation is going to be little complex as I want to fix it on the opposite wall, which is alright, just running conduits, but major issue; we had chosen to include garage for the exterior walls spray foam insulation at the time of construction (Here in Texas! we had wood working interest, we thought winter shouldn't stop us. The garage is so hot most part of the year, even early hours, heat never gets out and then there two ICE engines radiating heat when they are back in the evening, we had no idea). Anyway, now I have to cut open the dry wall on top of breaker box for running new line, can't see bunch of cables on the back, because there is spray foam. I have Installed/replaced electric box inside home on interior walls, that's the only electrical experience I got.
I am still deciding on the wall connector, I will mostly give up and let a professional handle it.
