Evidently my alarm system, conected to the autolocking system (fuse 17) ,as failed..erractic cycling of horn blowing when driving along. Very distressng! Has stopped with removal of autolock lock fuse. I believe the master control box lives under a floor board on right side passanger floor. Can anyone furhter guide me to disconnecting this box until I can get a replacemnt so I still have the ability to lock the card? (replace fuse 17) Thank you.
