Some clue as to the model you have might make answers a little easier.
At the very basic level wire it all in series.Brian - Newton Abbot, Devon, UK

Hi NZPOMME
This is a simple circuit if you look at one section of it at a time. Wire the HP/LP switch and thermostat (if you have an electronic thermostat there should be a relay which switches) in series to energise compressor relay or compressor if there is no relay. the start/run capacitors if any will have a wiring diagram with the compressor from the supplier.

The new compressor will have wiring instructions with it. Right down to terminal numbers for control circuit.
