Usually alarm horns are polarized - perhaps one pin has a red dot (positive)? Or do a search online for that make and model, pretty good chance someone has put up the info you need!

But, use a VOM to check each terminal for continuity to the mounting studs - and if there is continuity, that one will be the Ground. Pretty basic if this is for an automotive application where the frame often serves as a common ground. But, again, these days, alarm systems try to isolate key components and provide separate grounds so that they are less easily defeated. Peter Wieck Melrose Park, PA |
