Sensor Connection

Each controller has a unique set of sensor ZIF mating connectors. The schematics define
the number of pins and the BOM defines the vendor part number for each. The sensor
flex tails should be plugged directly into the controller connectors.
Note: ZIF connectors can be fragile. Do not force these connectors open. These ZIF
connectors are not removable; they must be opened/released to connect or disconnect a
cable from them.
Take the tail straight from the sensor and carefully align with the ZIF connector.
