Good idea - to answer your question, the XD9000
draws 460 Amps.
see www.total4x4.com.au/Info_Sheets/Warn.PDF
A hella battery isolator switch switch from

should be rated at 500+ amps.
3 options as I see it ... option 2 or 3 would be better.
1. Isolate the whole winch by inserting a high current switch in the +ve battery lead. Routing the cable into the cab will lead to losses in the cable so the whole circuit looses efficiency. Plus fire risk of unfused cables running through the firewall.
2. Same as above - but put the isolator switch in the engine bay just behind the grille and close to the winch. You only have to switch on at the beginning of a trip and off at the end.
3. Isolate the control lead - not the main mattery feed. For this you would need only a small switch - e.g. 5A which could be fused at the battery end. Much easier and no electrical loss.
Have fun!
