Most of the stuff can be cut away as its not needed in our systems.
Have you changed any of the piping yet, just from one of the pics it does look quiet right
With these system we use much smaller and longer capillary tube.
You wrap the capillary line around the cold suction line to help cool the refrigerant and remove heat before it goes to the evap head.
you also normally have a coil before the condenser to reduce strain on copper joins from the compressor vibrates when running.
With that air condition you need to figure out which is the condenser and what is the evaporator. If it’s a reverse cycle air-conditioned there is some tubing and electronics that arnt used. My suggestion would be to cut almost all of the wiring out and start again.
You will find that the fan on the condenser blows more air than needed, and might want to use the thermostat to turn the fan on when the condenser gets too hot, and switch off again when condenser at a good temp. Idelly you would be better using a smaller condenser and a 120mm fan, reduce the charge of flammable gas and also improve your temps at the same time.
Heres a propane pressure charge so you know what temps you get at what pressures.
