Abstract
Many devices, such as a turbocharger, use an apparatus to control their functions. For example, pneumatic and electric actuators are used to provide positional control of a mechanism on the turbocharger. The actuator must connect to the vehicles electrical system to provide suitable communication and control of the actuator. They must also have internal control and interconnection of devices such as sensors, electronic control unit, external electrical connector, and internal electrical connections. The electrical connections, placement of sensor, and placement of the controller are critical to the performance, reliability, and cost of the actuator. The control and interconnection system will provide the aforementioned requirements including a 'quick connect' capability for electrical connections and ease of assembly.
