This was installed on an MH34S Wagon R. I removed it today because I sold the car. I confirmed its operation before removing it today, and it worked without any problems. Included items: ① Main unit (TE-W5200) ② Remote control ③ Dedicated harness (TE87) ④ Immobilizer adapter (TE421) ⑤ Door lock unit (TE404) By installing the door lock unit (optional), you can lock and unlock the doors with the engine starter remote control. The instruction manual is missing, but you can view the instruction manual and installation instructions on the CARMATE website. If you have any questions, please ask, and I will answer to the best of my ability.
