Battery disconnection

[r500_wkd]

I want to remove the battery, check the state of the battery box, clean up what I suspect is a rusty earth connection in the back of the passenger footwell and clean up the Anderson connector as that too is very corroded.

I have Graham Varley's manual so understand how to disconnect the battery, but I'm paranoid about having a problem with things like the dash clock and immobiliser system (META) and end up causing more trouble than I'm trying to solve.

Any useful words of advice or reassurance out there?
