This location used to be listed on Tesla website but is no longer visible.
At the end of 2019, it used to say 2 connectors.
On Chargemap there are pictures showing the chargers in an underground parking. 3 wall connectors are visible in the pictures, 2 with the Telsla-only red sign and one with the all-EV white sign. Comments from as far back as February 2018 already mention there being 3 wall connectors, so it must have been wrong on the Tesla website since the start.
