Thanks for the wire specs, I also spotted that in Yoma's original post he put pin numbers on one of the images. Colours are different on mine, but most pins are the same, confirmed pin7 is heater and disconnected at control board. Interestingly, mine only has 7 pins - no interrupt. I have put in limited insulation - opposite side to the heater and from base of drum to just below the air vent. Instead of fire blanket, I used a silicone pot holder from The Reject Shop - they are selling them for $3 and they are 17.5cm square, waffle style about 8mm thick. It is a good fit between inner and outer casing, exactly the right length front to back, easy to cut to size and with the waffle texture, traps air beautifully. I may yet put another section in the opposite side, but this would interfere with airflow from the outside vent which may be a good or bad thing, so will wait until I better understand the somewhat bizarre airflow in the hottop before messing with that.
