Pros:

• Installed at the rear OBD port under the rear vent on Model 3/Y built between late 2020 and early 2025 (without Model 3 Highland).
• Only requires taking apart one plastic piece, which takes about 1 minute.

Cons:

• Does not provide access to features only available via the Front Installation, like Blind Spot Monitoring, Autopilot Penalty Prevention, and Muting the ISA system.

*On newer Model Y vehicles built between June 2023 and January 2025 (not Juniper), the rear OBD port can be moved from the back of the central console to the front left side of it, regardless of whether your car is LHD or RHD. See the installation video on our YouTube channel.

Pros:

Provides access to all features and automations available for Model 3 vehicles without a heat pump. In contrast, the rear (center console) installation does not provide access to CAN2 signals, which are required for blind-spot detection and speed limit sign recognition.

Cons:

Requires removing additional vehicle components and disconnecting the MCU connector, which is positioned at an awkward angle. However, the installation can be completed successfully by carefully following the installation guide.

A step-by-step tutorial showing how to access the MCU port on left-hand-drive (LHD) Model 3 vehicles built between 2018 and 2020 (without a heat pump). If your Model 3 is right-hand-drive (RHD), the procedure is identical, but the components are located on the left side of the vehicle.
