NBOX JF3 JF4 Reservation Lock Kit This is a reservation lock kit from Enlarge Shoji. I purchased it after taking measures to prevent battery drain. I used it in a vehicle equipped with an electric parking brake. It was installed for approximately six months. When installing and removing it, adhesive got on the cord, but it should not affect its use. Please refer to Enlarge Shoji's YouTube channel for installation instructions! Thank you very much!
