the switch wires to be used, you can usually simplify the instal- lation by locating the same wires in the vehicle’s kick panel. If no central locking switch is found, the installation may require a door lock actuator.

note: Always retest the wires in the kick panel to be sure they function the same way as the wires on the switch.

There are eight common types of door lock circuits (some vehi- cles use more unusual systems):

■Type A: Three-wire (+) pulse controlling factory lock relays. Most GM, some Ford and Chrysler, 1995 Saturn, some new VW, newer BMW.

■Type B: Three-wire (-) pulse controlling factory lock relays. Most Asian vehicles, early Saturn, some BMW and Porsche.

■Type C: Direct-wired reversing-polarity switches. The switch- es are wired directly to the motors. This type of system has no factory relays. Most Fords, many GM two-doors cars and trucks, many Chryslers.

■Type D: Adding one or more aftermarket actuators. These include slave systems without an actuator in the driver’s door, but with factory actuators in all the other doors. Type D also includes cars without power locks, which will have actuators added. All Saabs before 1994, all Volvo except 850i, all pre-1997 Subarus, most Isuzus, and many Mazdas. Some mid-eighties Nissans, pre-1985 Mercedes-Benz and Audi.

■Type E: Electrically-activated vacuum systems. The vehicle must have a vacuum actuator in each door. Make sure that lock-

Nissan specifications

Directed Electronics, a leading aftermarket automotive electronics company, has made significant strides in enhancing vehicle security, convenience, and connectivity, particularly with its products designed for Nissan vehicles. As one of the key players in the industry, Directed Electronics specializes in providing innovative solutions that integrate seamlessly with Nissan’s engineering.

One of the standout features of Directed Electronics products is the advanced vehicle security systems they offer. These systems incorporate smart technologies such as two-way communication, which allows the driver to receive alerts and confirmation signals through a remote control or smartphone app. This feature is especially beneficial for Nissan owners, as it provides peace of mind by giving them real-time information about the status of their vehicle, including unauthorized entry attempts or security breaches.

Directed Electronics also emphasizes remote start technology, a feature that is increasingly popular among Nissan owners. With the remote start system, drivers can start their engines from a distance, allowing their vehicles to warm up or cool down before they enter. This not only enhances comfort but also ensures that the cabin is at a more pleasant temperature, especially during extreme weather conditions.

Additionally, Directed Electronics products are designed with user-friendly interfaces and compatibility in mind. Many of their systems include mobile apps that enable drivers to monitor and control their vehicles from anywhere. This includes features like GPS tracking, which helps owners locate their Nissan vehicles in case of theft or if they've forgotten where they parked.

In terms of installation, Directed Electronics products are built to integrate effortlessly with Nissan models. Their systems often come with vehicle-specific wiring harnesses and detailed installation guides, making it easier for technicians to provide reliable installations that do not disrupt the factory settings of the vehicle.

Moreover, safety is a major focus for Directed Electronics. Many of their offerings include features such as impact sensors, tilt sensors, and glass break sensors that increase the effectiveness of their security systems. This proactive approach to vehicle protection resonates well with Nissan customers, who prioritize the safety and security of their vehicles.

In conclusion, Directed Electronics is committed to enhancing the driving experience for Nissan owners through innovative security, remote start, and connectivity solutions. Their advanced features, emphasis on safety, and seamless integration with Nissan models make them a preferred choice for those looking to upgrade their vehicle's technology and protection.
