1973 Chrysler “Security Alarm System”

Hey guys! Has anyone of you installed the "Security Alarm System" in his Landyacht from factory? In particular, it is about the Alarm Control Center (bottom left of the plan). This sits under the left front fender between battery and sheet metal. This box leads its own life with my boat, because apparently not all relevant contacts are installed. Does anyone have experience with it? Can this be bridged or uninstalled? If anyone still has such a part as nos, please report. I am grateful for...
