My usual question - have you got the manual? 🙂
The manual says to pull the pack out without disconnecting any of the cables or lines other than the steering box oil feeds, just spin it round 180 degrees once it's clear of the vehicle. I'm not convinced as it increases the risk of breaking something, so I lift the pack until you can get at the junction panel and then disconnect. This shows the pack going back in, nearly ready to connect up.
