The o-rings fit real snug in there. It caught me off guard at first too but then I saw how they seal and felt better.
Took the NB to Sound Station and Security. They are the stereo shop that did the remote start and they got it working again. Extremely happy. Also had them do a basic wash since it was filthy. The shop took care of me and clay barred the car without telling me. They have a customer for life.
