I purchased this on Amazon, but it's not compatible with the 5-inch model, so I'm selling it without using it. If you are currently considering purchasing this on Amazon, please consider this. Compatible models: Suzuki Jimny JB64W, Jimny Sierra JB74W, Year: July 2018 - Current Set contents: Idling stop canceller x 1 set; Material: ABS resin Easy installation: No need to cut and splice the original wiring or perform any troublesome wiring work. Simply open the hood and replace the connector near the grill without damaging the vehicle harness. Features: Idling stop canceller for Jimny. The idling stop function can reduce stress caused by delays in starting. It also has the effect of reducing the load on the engine. Enjoyable driving experience: The idling stop cancel lamp does not light up, eliminating stress from stopping at traffic lights; reduces battery consumption and prevents fuel efficiency degradation during idling stop; eliminates the discomfort of the air conditioner stopping while waiting at traffic lights.
