Plug the new sensor into the 4
pin insert. Align the notch on
the sensor PC board with the
notch on the back of the 4 pin
insert. Push in firmly by
holding the PC board. The
sensor will not seat fully down
into the insert, this is normal.
Carefully replace the sensor, gasket, and insert back into the
housing and reconnect each wire as shown. Note the location
of the notch on the insert and use that as a reference point to
orient each wire as shown below.
Thread the hex nut into the housing, securing the 4 pin insert
and sensor. The nut should only be hand-tightened.
