This cable allows you to connect to your 2012 through early 2015 Model S diagnostics port and access data like battery health and voltages/temperature, front and rear motor power/torque/voltage, 12V battery power/voltage, and much more.
For the DIYer that wants to have complete control this kit comes with an OBD-II shell, pins, strain relief and fasteners, you simply crimp the pins and screw together the connector shell. Includes Tesla connector with 2.5ft (~0.76m) of grey Belden 6509UE Plenum-CMP rated cable (see datasheet linked below). Other packages are linked at the bottom of this listing.
This setup is completely removable and doesn’t modify or damage the vehicle in any way. Product comes with a detailed pinout chart and instructions on how to access the diagnostic port (for either the yacht/carpet floor or those with a Tesla center console)
