Overview
The Tesla Model 3 has a "Power Conversion System" (also known as the "PCS") which contains both a 10kW AC charger and a ??W DCDC converter. The PCS is located inside the "Penthouse" part of the main traction battery system.

Hardware
Controller
Damien from EVBMW has designed a control solution which is open hardware, but closed software. Design files for the controller hardware are available on Damien's GitHub here. Licenses for the software are available through Johannes' OI webstore here. Controllers are also available as a fully-built kit (with pre-loaded software) on the EVBWM webstore here.
The PCS comes with different firmware versions some of which don't currently work with the above controller. We are in search of a solution.
Data Connectors
EDITOR'S NOTE: my research shows some conflicting/different part numbers mentioned - would appreciate some clarification here once validated
As per: https://openinverter.org/forum/viewtopic.php?p=26614&sid=24f0c02f437aeba37d4fc698d0ce54e6#p26614
The connector used for communications with the PCS :
https://www.te.com/global-en/product-1379662-5.html
https://www.mouser.ie/ProductDetail/TE- ... KwrJA1Y%3D
Pins: https://www.mouser.ie/ProductDetail/TE- ... DUA4Ad4%3D
In true Muskian fashion it seems they use the 1379662-5 natural color variant of the plug which has no coding tabs. It is of course unavailable from mouser. The black and green variants are functionally identical and should work with coding tabs removed.
However, as per: https://github.com/muehlpower/EV-FFB, there is also mention of 1318774-1 (white) or 1318774-2 (black) for the comms/data connector.
Power Connectors
The power-side connector assemblies are not widely available. The housings are a Tesla internal part (photos/part numbers here), however, 3D printable housings have been made available here. The terminals also aren't widely available, but are known. As per https://github.com/muehlpower/EV-FFB:
The contacts for 400V are Uni F630 from MTA, part number 1107940. For 12V Kostal PLK 14.5, part number 23124734300. The connector for the data is from TE connectivity, part number 1318774-1 for white or 1318774-2 for black.
