Set of remote starter ECU, harness, and installation manual. I understand it is compatible with all grades, both early and late models. It was installed on a late-model F Sport from 2018. Please prepare a separate remote control as there is none included. I used it with the premium model, so I believe it is compatible with the premium remote control (with smart key). - Remote starter ECU and dedicated harness - Installation manual included *Some knowledge of replacing audio equipment is required. It's relatively easy. I think it can be installed in 30 minutes. Please research initialization separately. The compatibility with the vehicle's computer needs to be done with a dealer computer, so please have it done at a dealer. (Toyota dealers are also acceptable.) With the genuine remote start, the smart entry (door unlocks when touching the door handle) of the smart key works without any problems. It also controls the auto lights. Thank you for viewing.
