The Thrustmaster TH8A circuit product works on the PlayStation 4 in the following way:

- Connectivity: You can connect the TH8A shifter either directly to the PS4 via a USB port or to the back of a compatible Thrustmaster steering wheel via a DIN connector.

- Compatible steering wheels: The TH8A is compatible with the Thrustmaster T150 Force Feedback, T300 Series and T-GT steering wheels. It can be connected via USB or DIN connectors.

- Switch plates: The TH8A supports two different shift plates: "H" pattern (7+1) and sequential (+/-). Both plates can be used depending on the game and steering wheel.

- Game compatibility: The TH8A is compatible with a wide range of PS4 games, including titles such as Assetto Corsa, Dirt Rally, and Driveclub. A full list of compatible games can be found on the Thrustmaster support website.

- Important notes: It is recommended to connect the TH8A directly to the PS4 and not via a USB hub. In addition, the latest updates for the TH8A should be installed to ensure correct function.
