Type C - Reversing Polarity
Interfacing with a reversing polarity system requires either two relays or one 451M (not included).
It is critical to identify the proper wires and locate the master switch to interface properly. Locate wires that show
voltage on lock and unlock. Cut one of the suspect wires and check operation of the locks from both switches. If one
switch loses operation in both directions and the other switch operates in one direction only, you have located one
of the target wires.The switch that lost all operation is the master switch. If one switch works both directions and the
other switch works only one direction, you have a Type A system. If both switches still operate, but one or more doors
have stopped responding entirely, you have cut a motor lead. Reconnect it and continue to test for another wire.
Once both wires have been located and the master switch identified, cut both wires and interface as shown below.
IMPORTANT! If these are not connected properly, you will send (+) 12 volts directly to (-) ground, possibly
damaging the alarm or the factory switch.
Type D - Aftermarket Actuators
In order for this system to control one or more aftermarket actuators, a 451M or two relays (optional) are needed.
Vehicles without factory power door locks require the installation of one actuator per door.This requires mounting the
door lock actuator inside the door.Other vehicles may only require one actuator installed in the driver's door if all door
locks are operated when the driver's lock is used.This type of installation is required to operate factory lock systems
in Volvo (except 850), SAAB, and most Mazda, Isuzu and Subaru models.
The fuse used on 12 volt inputs should be 7.5A per motor installed in the vehicle.
IMPORTANT! Do not connect the outputs of the alarm directly to the actuator!
