New System Mounted Pressure Transducer Featuring Local Interconnect (LIN) Network Technology!



  • Increased ECU efficiency
  • Faster communication
  • Accurate and reliable supply of information
  • Elimination of interruption or disturbance from competing electronics
  • Faster identification of problems or failures
  • Reduction in the amount of wires in complex wiring harnesses and more

What is Local Interconnect Network (LIN) Technology?

In the initial years, the practice was to have stand alone autonomous electronic systems. It was soon realized that there was a need for a mechanism to enable systems to communicate with each other. This led to the introduction of networks such as serial communication channels (bus) that would coordinate the individual electrical systems and lead to improved functionality of the vehicle as a whole.

Today, and as vehicle design continues to progress, modern vehicles offer more electronically assisted or electronically controlled systems than ever before. These modern enhancements benefit manufacturer and end-user alike, increasing safety, reliability, fuel economy, ride control, driver and passenger comfort and many other things we’ve come to rely on and expect. These upgrades to key areas of the vehicle go hand-in-hand with the addition of more and more smart sensors that deliver critical data to on-board computers.

LIN, stands for Local Interconnect Network, a serial network protocol used for communication between components in vehicles. Local Interconnect Network (LIN) eliminates all sensors operating autonomously within the vehicle and links them onto a network together, allowing the sensors to communicate in a fast, reliable and secure way with on-board computer controls such as the ECU. Added benefits are; increased ECU efficiency, faster communication, elimination of interruption or disturbance from competing electronics, faster identification of problems or failures, a reduction in the amount of wires in complex wiring harnesses and more.

With the release of this Everco® HD pressure sensor with Local Interconnect Network (LIN) technology from Trensor®, Everco® HD pushes far ahead of the competition with cutting edge technology never before offered in the aftermarket. The Local Interconnect Network (LIN) sensor replaces the OEM A/C system high side pressure sensor in many Audi, Volkswagen and Skoda vehicles (replacing OEM numbers 4H0 959 126 A, 5Q0 959 126 A and others) and brings a fresh approach to competitive technology in the marketplace. Everco® HD proudly boasts a replacement product that exceeds OEM design, quality and reliability. With automakers trending more and more toward these high-tech networking solutions, you can rest easy knowing you have a true technology partner by your side.

Blower Motor Resistors

15 NEW Blower motor resistors connectors that fit 139 resistors, total VIO 65,888,327

Everco® HD is committed to being the best, offers hundreds of high-quality connectors to help to do the job right the first time. These connectors utilize high grade materials to ensure peak conductivity and perfect connections.


Why do you need these connectors?

When a blower motor resistor fails, it’s recommended to replace the connector. A blower motor resistor connector connects the HVAC control module and the blower motor resistor. The connection between the electrical terminals of the blower motor resistor and the wiring connector that powers the module may be incapable of conducting higher current levels for sustained periods of blower motor operation. In addition, moisture and other contaminants may enter the fresh air intake and corrode the terminals. If any of these were to occur, the blower motor resistor or wiring connector could overheat and burn.

By replacing connectors every time we can ensure the connection between the HVAC and the blower motor resistor is optimal.
