The module is not visible in the picture but it's up, left from facing inside the opening and don't pull it. Just pull the large grey connector with one large dia black wire (ground) from it (pinch release). If you have already disconnected the ground at the battery this would be redundant.

 

It was pretty much the first thing I looked for, once I've had SDD operational.
And (with gold key access) there is an entry "stop/start-system" which can be used to switch it of permanently, or at least until you switch it back on with SDD.
I prefer this way over pulling plugs, and shutting down any battery state monitor, even if there are no immediate consequences
