I recently got a mustang from a friend who had a line lock installed and said all I need to do is hook up the ground wire..it is a jegs line lock an there instructions aren't the best..all of The brake lines are hooked up correctly I believe..but when I was re installing the arming button an a activation led light the lock doesn't seem to engage..I don't know what I am doin wrong..it seems like such a simple install..if anyone has any tips..or videos or web links other than jegs to help instal Thad b really cool

 

Any help would b nice..
