well i fixed it
the problem wasn't pushing it in - when i pushed it in, it got stuck in - so i pulled it and it clicked then it's working again now..
you guys think my odometre has been wound back? i guy i know looked at the seal around the box and it seemed to have not been tampered with - the car was brought over here decmeber last year and had 4 k's on it after comliance - japan is a small place
