Thanks again for the reply and wiring diagram Alan.
I have ordered the parts however, i didnt go with the Jaycar Thermostat switch you provided a link for because of its flat base and mounting options because of this would be limited.
After some investigation, have discovered heat is the greatest at the pipe that exits the compressor and the beginning of the condenser .... That pipe in question has an outside dia of about 6mm condenser...... And then thought, maybe a control switch that has a corded probe (similar to the ones we use to measure inside fridge cabinet temps.
I tested the efficiency of readings using one of my digital fridge cabinet thermometers where i tightly tapped and bound the probe hard against the side of the condenser pipe and was happy with how it performed. With the 15 litre running at full freeze mode, that pipe would heat up to low 50's in celcius all while ambient temperatures were mild mid 20's.
I found this that i think will be ok

I am hoping this will work ok.....
Before i go, i will add some advice for those Engel owners that may want to take on this mod themselves.
Before proceeding, check the power supply for your fridge and make sure the power supply is not fully enclosed in a sheet metal box/case..... If it is, its near impossible to cut into the 12 volt supply feed to power your thermistat and fans.
I have 2x same model 15 liter Engels that were manufactured some years appart. during this time there must have been a design change. One of the models (later model) has the enclosed power supply that goes full length from where the power cords plug in, right up to where the AC transformer is. Impossible to access this case to cut into the 12 volt supply, unless of course the power supply is removed which would be a major task indeed..... The earlier model 15 i have here, thank god the power supply case finishes short of the plug base (where the 12 + 240 v cords plug in) so all the wires are exposed before the dissapear into the power suppliy case.......
I hope i have confused :-(
