Replace the o-ring seals with new lubricated seals.
2.
On the new temperature sensor cables, strip the end of
each cable and crimp pins to each stripped cable.
Tip:
If you do not have the necessary tools to do
these operations on the cables, another solution is
to keep the old cables connected to the connector,
cut them at mid-length and solder the new cables
to them.
3.
Slide the cables through the temperature hole and
through the hole in the internal housing and put the new
cables into the white connector in the same order as on
the picture (view of side with clips upward).
