Type D: After-market Actuators
In order for this system to control one or more after-market 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.
Type E: Mercedes-Benz and Audi (1985 & Newer)
Door locks are controlled by an electrically activated vacuum pump. Some Mercedes and Audi models use a Type
D system.Test by locking doors from the passenger key cylinder. If all the doors lock, the vehicle's door lock system
can be controlled with just two relays (optional). The control wire can be found in either kick panel and will show
(+)12V when doors are unlocked and (-) ground when doors are locked.
To interface, see diagram below. The system must be programmed for 3.5 second door lock pulses. (See
System Features Learn Routine section of this guide.)
