Red Wire (Constant Power); Yellow Wire (Ignition Input); Orange Wire (Output While Armed) - Crime Guard 328i3 Installation Manual

Red Wire - (Constant Power Input):
The Red wire's function is to supply Constant Positive 12 Volts for
security system's operation. When 12 Volts is first applied to the Red wire,
the system will revert to the state in which it was in when power was taken
away. If the vehicle to be serviced, especially if it involves the battery, the
system should be placed in Valet Mode. This will prevent the system from
being activated if the battery is disconnected and reconnected. The Red wire
also supplies 12 Volt Positive to the module's internal relay for flashing the
parking lights.
CONNECTION: Connect the Red wire to a Constant Positive 12 Volt
source. This source should have Positive 12 Volts with at least a 15 Amp
capacity at all times and in all ignition key positions. Connection locations
can be at the supply wire at the ignition switch, the supply wire behind the
fuse block or the fuse/junction block. Never just insert the Red wire or any
other security system wire behind a fuse. Also, please note that connecting
directly to the battery's Positive terminal will expose this connection to failure
due to a corrosive environment unless the connection has a protective
coating.
Yellow Wire - (Ignition Input):
The Yellow wire is an ignition "on" input to the security system. This
connection is critical to the proper operation of many of the security system's
features.
CONNECTION: This wire supplies Positive 12 Volts to the control
module whenever the ignition switch is "on". This connection should be
made at the ignition switch harness, to the primary ignition circuit. Primary
ignition has 0 Volts when the ignition key is in the "Lock", "Off" and
"Accessory" positions; and Positive 12 Volts in the "Run" and "Start"
positions. Locate the correct wire at the ignition switch harness and securely
splice the Yellow wire to it.
Orange Wire - (Output While Armed):
Starter Interrupt Optional On 328i
Starter Interrupt Standard On 533i
The Orange wire is a Negative starter interrupt output, which is active
whenever the security system is in an armed state.
CONNECTION: To interrupt the vehicle's starter circuit, the starter wire
must be located, identified and cut. Cutting the vehicle's starter wire will result
