JB23 Jimny, early model with harness A self-made instruction manual is also included, so I think it can be easily installed. Before listing, I have checked the item, so I cannot respond to issues such as not being able to install it or start the engine. Since it is used, it is basically 2N (no claims, no returns), Please purchase with your understanding. Installation is at your own risk. Be sure to perform the initial settings written in the manual. Please judge the condition of the product from the photos. It has a turbo timer, so I think it's very good. First come, first served. Thank you. I have tested it and there are no problems with the operation, but I cannot accept returns if you say it doesn't start. So far, 100% of the returned items have worked fine. Also, since it is an electrical component, I will treat it as junk. (Added November 21, 2022, 9:16 PM) Recently, a person named daddy sinceity purchased the item on another site and said the engine wouldn't start. I thought it might be a initial defect, so I kindly exchanged it for a different one. However, the engine started properly, and since the exchanged item was very rare, I asked for it back. They then became angry, saying that I was the one who offered the exchange, and even left a negative review. Therefore, I will not accept returns or exchanges. I offered this out of kindness, and it's disheartening to be treated this way.
