DISCLAIMER: DO NOT DO THIS DO NOT DO THIS DO NOT DO THIS
After discussions with
@JWardell and
@Ingineer, we were able to confirm that the tesla ccs adapter is entirely passthrough and just acts as a physical adapter, with no internal circuitry. The reason this works is because the newer cars have CCS communication capability built into the charge port ECU. If your car is older than (insert date I don't know here), this will just make your setec useless, because the car won't natively speak CCS.
Also: I added temperature sensors to ensure this safely disconnects the pilot if there is heat buildup. DO NOT DO THIS AT ALL, BUT IF YOU DO, DO NOT LEAVE THIS UNATTENDED!!
All of that said, I have now improved my Setec by gutting it and making it passthrough. My first test at a station worked fine, and looking forward to seeing if I can hit 150kw on my road trip, which begins tomorrow.
