1. disconnected built-in a/c thermostat
2. drilled hole to mount new thermostat
3. routed temperature probe inside spare copper tube up into igloo (required additional hole)
4. using spare wire, connected thermostat to a/c power control
5. spliced in pump power cord (see thick black cable) for continuous running
6. summary: routed wires through a/c on-off switch; any on position turns on the thermostat, which in turn controls the compressor. pump is always cycling.
