Mine was 3m taped to the casting between the 2 mounting screw posts on the passenger side of the frunk. However l, when I removed the trunk liner everything was wet and dirty. I had not counted on how open to the road and wet the inverter would get. So, I decided to add length to the 48V wires...
Red is positive
Brown is ground
Green is not used
Cables were long enough
Went with this plug instead of the original I listed, since it plugs directly in to the Victron Inverter,

I updated the install with a better outlet for the frunk. Cybertruck 48Volt wired to inverter inputs. The power outlet simply plugs into the 120Volt outlet on the inverter and drill a 1-3/4” hole in the frunk liner and insert the power outlet. Install complete.

I also wanted my cooler in the frunk and it draws only 48W. I also wanted more versatility for other powered options in the future, so I went with this setup. 48 Volt to 120 Volt and used the Ford outlet that is rated for the max 400W on the auxiliary outlet in the frunk.
