    There is great technical information on the diagnostic port (TDC - Tesla Diagnostic Connector) in the forum but as I found it difficult to find in the different threads, I started an index. Please comment with corrections or additions.

    Why access it?
    To access more and more granular car diagnostic information that can be obtained by the apps that use the online Tesla APIs. Motor torque for example. Or battery temperatures.​

    Where is it?
    Between the front screen and the cubby. Pull the front of the cubby down to access. Don't pull the cubby out (just down) on the older cars or it is hard to reinstall.​

    Change in Connector

    The connector changed on Sept 2015. What approximate VIN is that?​

    Unanswered Questions
    Can multiple diagnostic connectors be used at the same time on a splitter? If so which?
    How long of an extension and\or splitter can be used reliably?
    Will Tesla disable the diagnostic port like they disabled the collocated Ethernet port?​
