From a friendly driver, I got this picture. No, not his ZOE.
The most interesting part in my opinion was the location of the TCU.
It is that black box on the far right side of the picture. Wrong. It is not in this picture, situate behind R-Link and in front of the windshield vents. Damn hard to replace!
The open bracket under it is the mount for the radio module, you can see the white coaxial connector dangling just next to the insulation mat. Think of it like a traditional car radio form factor but without a front.
Lots of unidentified stuff, such as the black box under the center ventilation vent. Maybe it’s the climate computer. From what I understand the two boxes under the ventilation panel area are the fragrance / ionisation controller and a multimedia gateway.
