Installation Instructions:

1. Disconnect the power
Make sure the vehicle is powered off.
2. Remove the old harness
Find the original transmission harness connector of the vehicle, loosen the harness fixing buckle or bolt, gradually disconnect the harness from the transmission control module (TCM), and remove the old harness.
3. Match and connect the new harness
Connect the plug of the new harness to the corresponding interface of the original vehicle harness or transmission control module according to the color code or label of the harness.
4. Fix the harness and restore the connection
Use the wire harness fixing clip to ensure that the new wire harness is fixed along the original path to avoid contact or friction with high-temperature components. Reconnect the battery and check whether the plug of the transmission control module is firm.
5. Functional testing and debugging
Start the vehicle, check whether the transmission shifts normally, and confirm that there is no fault code through the OBD diagnostic tool.
6. Note:
If you have any questions, it is recommended to consult a professional technician.
