Constant Power
Red Wire
The Red wire supplies constant (+) 12 volts for the security system's operation, which includes supplying the built-in relay contacts for flashing the parking
Please note that when (-) ground and (+) 12 volts is first applied to the control module, the system will revert to the state it was last in.
CONNECTION: This connection, like the Ignition Power and Starter Disable, is best made as close to the ignition switch as possible. We urge you to use
an Omega Research and Development Quick Interconnect Harness. A Quick Interconnect Harness is an adapter wiring harness which plugs into an existing
pair of the vehicle's stock connectors, with circuits needed for the security system branching off to a connector which plugs into the security system. If you're
not using a Quick Interconnect Harness, follow the remaining text.
Caution: Be aware of, and avoid, any airbag circuitry. Due to the fact that an installer will not be in a normal, upright seated position, severe injury may occur
in an accidental airbag deployment. Also, use of a volt-ohm meter or multimeter instead of a testlight will greatly reduce the risk of an accidental airbag
deployment. The target wire will have (+) 12 volt positive at all times and in all ignition switch positions. Another location can be at the constant (+) 12 volt
wire behind the fuse block or the fuse/junction block. Never just insert
this wire behind a fuse. The connection location must have
constant (+) 12 volt, 15 amp capacity. Connecting directly
to the battery's positive terminal is not recommended
due to the corrosive environment. Caution: The
Constant (+) 12 volt wire at the ignition
switch may not be fused! Extreme care
must be taken not to short this wire! If
you plan on disconnecting the battery,
always check the car's owner manual
for any cautions or special procedures
involved when disconnecting the vehicle's
battery. The complexity of a modern vehicle's
engine management and body computer systems,
in addition to the presence of air bag systems, may
have an effect on how the battery is disconnected,
how long it is disconnected, how it is reconnected, and what, such as computer learning procedures, should be done after
reconnecting. Also check the vehicle's owner's manual section on fuses. If the Constant (+) 12 volt wire to the ignition switch is fused, the fuse or fuses will
be identified in that section of the owner's manual. Generally, older cars do not have fuses protecting the Constant (+) 12 volt wire(s) to the ignition switch,
but rather, in most cases, a fusible link. Most newer vehicles, however, do have a fuse, usually in the form of a Maxifuse. This fuse, or fuses, are normally
identified as "Ignition Switch" and are usually located in the engine compartment, housed in what may be described in the owner's manual as a "Underhood"
