Give your Model 3 Highland the OBD2 connection it's missing!
This specially adapted adapter makes it possible to read vehicle data and connect equipment that requires OBD2 communication - quickly, easily and without affecting the car's original wiring.

Optimize your data collection

The adapter allows you to use popular diagnostic apps and hardware, such as: Scan My Tesla, to monitor:

• Battery health and charging status

• Temperature values

• Engine power output

• Other real-time data from the car's CAN bus

Prepared for control current systems

The adapter is also compatible with XBB system, which makes it possible to retrieve control signals for the installation of, for example, additional lights or other equipment.

Installation – easy and safe

The adapter is mounted between existing connectors in The A-pillar on the passenger side.
It does not affect the car's functions and does not require any modification of the original wiring.

Tip: Leave the OBD2 port at the front of the cabin if you want quick access to diagnostic tools in the future.

Important before installation

To avoid damage to the vehicle's electronics, the car must be completely de-energized before starting work.
Tesla goes into sleep mode after approx. 8–10 minutes – wait for this before disconnecting any contacts.
If you want to be extra safe, you can also disconnect +12V terminal during installation.
