Okay i've got a few wires i need to get switched power for, i understand i can tap into the green wire but is it safe for so many things?
Whats the proper way of getting switched power? Is there anything in the fusebox i can use?
Thanks

Depends entirely what you're connecting. The K9 relay position in the fusebox can be configured to provide switched power, as is done in the touring for the rear wash/wipe.
There are relays K5 and K7 already configured, of course.

Air pressure gauge and air suspension ECU
I've already spliced it once for the EWS.

Shouldn't be any great power consumption there, assuming the air pump itself is powered from a fused unswitched live.
You don't want the pump working at the same time as the starter motor though, so best to take the power from K5 or K7.
If you don't have heated seats, there is a 'spare' feed from K5, via fuse 16, available at a white/brown wire at the accessories socket. This wire wasn't fitted on some lesser models, so check that there's a bucket fitted in the outer position for fuse 16 as a first step.
