    Diagram of powertrain components and their connections?

    Does anyone have a diagram of the powertrain components and their logical connections? It would be helpful to have a map of how drive units and controllers connect to each other and a bonus if there’s any additional CAN data. For context I just want to understand the differences between the...

    Sending commands on the CAN bus: like S3XY Buttons

    Hi. Looking at the S3XY buttons, they come with an OBD2 adapter. Since I already have an OBD2 adapter to run ScanMyTesla, my port is in use and I see no way to piggy-back adapters.

    Plaid CAN bus adapter

    Can any Plaid owners confirm if the connector to the CAN bus is the same as previous Model S? It was previously behind the panel under the screen (shown here).
