Michał Gapiński(@mikegapinski):I have a feeling they didn’t make the HW4 with any kind of retrofits in mind, harnesses with relocated pins that do the same thing, mounts that don’t fit, different windshield needed, headliner trimming required to fit the mirror assembly etc. It can be easily done with their resources, but it needs brand new parts made just for the retrofit.

What if I told you that it’s over? All cameras functional and she rips like there is no tomorrow? It was a nightmare after all the early optimism, front windshield needed replacement and there is still some refinement that needs to be done. First HW3 Tesla converted to HW4. And it all started with a naughty esp32 and a dream 🤣 Kudos @maciej, it’s been a long journey. I have a feeling the next one will be even more interesting (some soldering required)
