Installing the ESP Sensor with Single Wire to the Motor
It is recommended that the sensors be installed in a controlled environment or shop
prior to being sent to the field. If a sensor must be installed in the field follow the
procedures outlined below for sensors equipped with single signal pin.
Spy Pro gauges are pre-wired with a connector pigtail adapter and waterproof boot seal
attached to the gauge signal pin (see illustrations below). For optimum performance,
connect the motor WYE point or I-Wire directly to the gauge pin. This will require
removal of the gauge motor head adapter (if fitted) to access the I-Wire pin on the
gauge and re-fit of the motor head adapter. If the motor head adapter is removed, re-
torque the head as required for your application.
1. Connect the male end connector by fully inserting into the female connector from
the motor I-Wire. FIGURE 8
