On to the smoke box. Removing all of the screws from the back of the smoke box,
one can see the power coming into the unit from the bottom, the wires to the
heating element, and wires running to the over-limit switch just to right of center
in the picture



I drilled a 1/4" hole just to the right of the thermal switch to mount the thermocouple.
The material lining the box is very thin, so a light hand, sharp drill bit,
and something to back up the hole is useful to not tear it.



I tilted the panel back onto the unit, and marked THROUGH the hole to drill for
the thermocouple leads -- then drilled another 1/4" hole through the rear
cover.
