testing reversing polarity systems

Use these instructions if the power door lock switch has four or five heavy-gauge wires. This type of switch has two outputs that rest at (-) ground.

important: To interface with these systems, you must cut two switch leads. The relays must duplicate the factory door lock switches’ operation. The master switch will have one or two ground inputs, one (+)12V input, and two switch outputs going directly to the slave switch and through to the motors. These outputs rest at (-) ground. The lock or unlock wire is switched to (+)12V, while the other wire is still grounded, thus completing the circuit and powering the motor. This will disconnect the switch from the motor before supplying the motor with (+)12V, avoiding sending (+)12V directly to (-) ground.

Directed Electronics Nissan manual Testing reversing polarity systems

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.
