To install the Connects2 CTSTY019.2 Steering Wheel Control Interface in your Toyota vehicle, please follow these steps:

1. Remove and disconnect the factory stereo according to the vehicle owner's manual or consult a fitting professional.

2. Connect the 12 Pin connector from the stereo connection (patch) lead to the interface box. Refer to the wiring diagram on page 4 of the manual for more information.

3. Connect the opposite end of the stereo connection (patch) lead to the steering wheel control input on the back of the aftermarket stereo. The type of connector may vary depending on the brand of the aftermarket stereo. Consult the aftermarket stereo installation manual for further information.

4. Connect the 20 Pin connector from the supplied wiring loom to the interface box.

5. Connect the power/speaker ISO connector to the power/speaker ISO connector at the rear of the aftermarket stereo. If your aftermarket stereo does not have an ISO connector, refer to the "Wiring Key" on page 2 of the manual for information on which wires to connect.

6. Connect any additional wiring, AUX connectors, and the Yellow RCA connection to the aftermarket stereo's wiring harness where required.

7. Connect the vehicle-specific power connectors on the supplied harness to the OEM connectors from the vehicle.

8. Test the stereo and steering wheel control functionality to ensure correct operation before reassembling the dashboard. If the steering wheel control functions are unresponsive, uninstall the interface and wiring and reinstall carefully following the above steps.

Please note that technical knowledge is necessary for installation, and it is recommended to read the manual thoroughly before proceeding. The installation location should be free of moisture and away from heat sources. Using the correct tools during installation is important to avoid damage to the vehicle or product.
