I need some help with my fridge constrol/thermostat wiring

Hey fellow Brew(Pi)ers,

I started my BrewPi fridge build today and I could use some help with the wiring.

My fridge has a fan inside, other than that it’s pretty standard (only fridge, no freezer chamber) I guess. I want to do method 2 from the fridge hacking guide (https://www.brewpi.com/fridge-hacking-guide/), so basically I want to go around the fridge control/thermostat so it won’t interfer.

Here are some pictures, maybe you guys can help me out and tell me which wires have to be connected.




green/yellow should be earth, brown is live but I’m not sure about the grey “double wire” and the red one. Maybe the red one is the connection to the fan?
