Thank you for viewing. This is an engine starter set made by Circuit Design. A multi-adapter for Toyota vehicles is also included. Winter is just around the corner, so how about getting one now? This starter was installed in a 20 series Alphard, but I am selling it now, so I had the dealer remove it. As you can see, it is a used item, so please refrain from purchasing if you are looking for a new item or something close to new, or if you are sensitive to such things. Everything shown in the images is included in this sale. As you can see in the images, the antenna on the remote control is slightly tilted, but it did not cause any problems during use. It has a simple structure, and the engine starts with a "beep" sound when you press the yellow button. It stops when you press the gray button. Instructions are not included, so please search online. As I am a novice, the coupler connections are left as they are. Please have someone with sufficient knowledge of vehicle maintenance handle the installation. Please understand that we are not responsible for any problems after installation. Since it is unidirectional, there is no answerback to receive when the engine starts, so the remote control will not respond even if the engine starts. Depending on the radio wave environment, it worked without any problems in the parking lot away from my workplace. I think there are no problems with the operation itself (the remote control has been confirmed to beep. The main unit has not been confirmed since removal). Due to the nature of precision equipment and aging, please understand that we are not responsible for any product troubles after arrival, including shipping conditions and natural disasters. As a standard, cancellations and returns after purchase are not allowed, and we cannot accept any claims. Please fully understand the above contents and make your decision after careful consideration before purchasing.
