Thank you for viewing. I have listed this item due to a request. The main unit was working normally until removal. The immobilizer adapter is the type that attaches copper wire around the engine key. I don't know the wiring, so please search online. It's the type where you put the engine key inside. Please understand that this is a used item before purchasing. I will include installation instructions, but please note that I cannot provide after-sales support. Also, please install at your own risk. It has an answer-back function. It's free shipping, so I can't lower the price. Thank you for your understanding. Please judge the condition of the product from the photos. The tightening part of the immobilizer adapter was broken, so I glued it with Aron Alpha. I listed this item at your request, but since I have never actually installed it, please consider it as completely junk. Basically, please use the 2N rule (no returns, no exchanges). Recently, a person named daddy sinceity purchased this item and said the engine wouldn't start. I thought it might be an initial defect, and as a courtesy, I exchanged it for a different one. The engine started properly, and the exchanged item was very rare. When I asked for it back, they got angry and said, "You said you would exchange it!" and even left a negative review. Therefore, I will not accept returns or exchanges. I did this as a courtesy, and it's disheartening to be treated that way. I am also listing Yupiteru and Comtec JA11.JA12.22JB23 early model engine starters and turbo timers, so please take a look.
