Stare at thermostat. Figure out how to wire the power in and out.
Cut the clicky on/off switch out of the light fixture cord.
Split both cut ends of the light fixture cord apart and strip 1/2 inch off of both ends.
Cut two holes into the wall of the cooler for the power cords for the thermostat and PC fan. Run the wires through the holes.
Wire unribbed side of light fixture cord into thermostat. Join with other piece of unribbed wire. Splice together the ribbed side of the cord.
Install light in Incubator. I cut a hole in the hardware cloth and snapped the fixture into that hole.
Cautiously plug in to see if light works.
Undo any tripped breakers and wire it the other way if you did something wrong.
Cut the end of the transformer (the part that plugs into some unused machine, not the part that plugs into the wall). Separate the cords and expose 1/2 inch of bare wire.
Splice the wires of the PC fan and the transformer together.
Cautiously plug that in to see if it works.
Undo any tipped breakers and rewire appropriately.
Cover bare wires with splicer caps or electrical tape.
Install fan and thermostat into incubator using twistie ties through the walls of the cooler.
Check again to make sure it all works.
Enclose electrical stuff behind hardware cloth guard.
Cut a hole in top of the cooler smaller than the glass. Tape glass to top of cooler from the top.
Poke 4 air holes at the bottom and two larger holes (plug with paper towel wad or corks) to regulate humidity.
