Obviously the relays will need to be earthed.
The live does not connect to the switch (it can't, hence the why a relay is used).
The relay ground connects to the fan switch, when it closes this then completes it's circuit and in turn the live to the fans.
This is the OE setup, and all models are the same.
Your diagram shows this.
