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 
ashing 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 “
...
“ transmitter is held for 3 seconds. The timing 
is congurable 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 ashing lights are not desired, this output can be congured to operate as 4th 
channel using feature #7.
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.
  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 exibility 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 specic 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 specic information for more details.
