Thank you for viewing! It was working perfectly until removal. Please understand that this is a used item before purchasing. Installation instructions will be included, but please note that we cannot provide after-sales support. Also, installation is at your own risk. Basically, I'm looking for 2n. This is for AT vehicles, but it can be installed on MT vehicles. However, please do not leave comments saying things like "I can't install it" or "Installation is at your own risk." If you want to install it on an MT vehicle, I think the COMTEC engine starter I have listed is more reliable. Thank you. Please judge the condition of the product from the photos. I also have Yupiteru and COMTEC engine starters for JA11, JA12, and the early model JB23, as well as turbo timers, so please take a look at those as well.
