Crime Guard 328i3 Installation Manual page 13

CONNECTION: Connect the Green wire to a wire in the vehicle which is
common to all of the door pin switches; the correct wire in this type of dome
light/door jamb pin switch system will have no voltage present and will also
show chassis ground when the doors are opened, and up to 12 volts when
the doors are closed.
Typical Negative Switching Dome Light System
Note: The Driver Pin Switch often
will have an extra wire that goes to
the Ignition Key Warning. This cir-
cuit will trigger the security system,
but only from the driver's door; this
is the incorrect activation wire.

Notes, both types of dome light systems: The correct wire will show this
change when any of the doors are opened. If the vehicle has delay dome
lights, remember to take this into account when testing the wire. If the pin
switch is mounted in the metal structure of the vehicle, and the dome light goes
out when the switch is removed, suspect a grounding-type dome light
system. While the traditional pin switch is mounted in the front door jamb
area, also be aware that many vehicles utilize other types of switch devices
to operate the interior lights. Some imports have a sliding type of switch and
many have the pin or sliding switches in the rear door jamb area. In addition,
some vehicles utilize switches in the doors, either connected to the exterior
door handles or to the latching mechanism. A vehicle which has the dome
lights illuminating when the exterior door handle is lifted is an example of this
type of switching system. Also be aware of vehicles which diode-isolate each
door. Typically, this is usually encountered with dash displays that indicate
