Secondary 7 Pin Harness; Door Lock Connections - Omega REC-12 Owners & Installation Manual

Wiring Connections (cont'd)

SECONDARY 7 PIN HARNESS

YELLOW/GREEN: (-) OEM Alarm Disarm Output- This wire mimics the bLUE
unlock wire and is used for disarming factory installed alarm systems. It is a
250mA negative output.
BROWN: (-) Horn Honk Output- Connect this to the vehicle's horn switch cir-
cuit. It is a 1A negative output that is directly compatible with most horn circuits.
Add a relay if the vehicle requires higher amperage or positive polarity.
WHITE/RED: (+/-) Flashing Light Polarity Selection- This is the input to the
flashing light relay. Connect the bullet connector on the end of this wire to the
mating connector on either the RED (+) or bLACK (-) wire to select the desired-
polarity. The polarity is determined by the vehicle's light circuit.
PINK: (-) 3nd Channel Output- This wire, by default, has a 1 second 250mA
...
negative output whenever the "
is configurable with feature #12. It is typically used to activate accessories like
a remote start unit.
WHITE: (+/-) Light Flash Output- by default, this wire is connected to the ve-
hicle's parking light circuit. It's polarity is determined by the WHITE/RED wire.
If flashing lights are not desired, this output can be configured to operate as 4th
channel using feature #7.

" transmitter is held for 3 seconds. The timing
WHITE/BLACK wires: (+/-) Domelight Supervision Output- by default, these
wires will turn on the vehicle's interior lights for 30 seconds after unlocking by
the transmitter. Connect the FUSED wire to either +12v or ground, depending
on the vehicle's light circuit requirements. Connect the NON-FUSED wire to the
domelight circuit in the car.

DOOR LOCK CONNECTIONS

The REC-12 has a 4 pin plug-in door lock/unlock port. It provides 3
250mA outputs for LOCK, UNLOCK #1 (driver's OR all doors), and UNLOCK
#2 (all doors for driver's priority). It also has a constant +12V output for power-
ing optional relay coils. It offers installation flexibility because every doorlock
interface available from Omega R & D, Inc. will plug directly into this port. There
are 4 primary types of analog doorlocking systems used in vehicles today.
Additionally, there are digital databus driven systems that require an interface
module. Refer to vehicle specific information to determine which doorlocking
system is used.
Mutliplex Doorlocks: This is the newest type of analog doorlock
control system developed for vehicles. It typically uses only 1 wire for lock and
unlock control. It can be positive or negative and the vehicle's body computer
looks for multiple signals on this wire. Each signal differs in voltage. This is
controlled by resistors in the doorlock switch which must be mimiced by the
doorlock interface. Refer to vehicle specific information for more details.
