Thank you for viewing. It was working normally until removal. Please understand that this is a used item before purchasing. Please note that we cannot provide after-sales care. Also, please install it at your own risk. For the immobilizer adapter, remove the cover under the steering wheel and install it. If you don't know how, please Google it. I cannot provide instructions, so thank you for your understanding. Basically, please use the 2N rule (no returns, no refunds). For AT (automatic transmission) vehicles. Please judge the product condition from the photos. I am also selling Yupiteru and Comtec JA11, JA12, 22, and JB23 early model engine starters, turbo timers, etc., so please take a look at those as well.
