Default Getting into the trunk when the battery is disconnected

The procedure for opening the trunk when the battery is dead is well known and documented in the owner's manual. (Apply +12VDC to the marked points at the engine fuse box and press the trunk open button.)

Occasionally people ask how to get into the trunk when that method fails to work, for example if the battery is removed from the vehicle or if there has been water damage, an accident, of the CJB fuse box is dead. In those cases we have resorted to removing the rear seats, removing the rear bulkhead harness grommet, pushing down the rear carpet and fishing for the emergency release cord with cable rods. That works, but the workshop manual on TOPIx (https://topix.jaguar.jlrext.com/topix/vehicle/index) has been updated with the following for all vehicles from 2010 onwards (i.e. all X351s):

In the event of the luggage compartment lid failing to open due to a system fault there is an emergency electrical release connector situated behind the rear seat squab next to the CJB. The connector is linked to the luggage compartment lid latch actuator.

A +12 volt feed applied to the connector will power the luggage compartment lid latch actuator to an un-latched state.

As the CJB controls the latch release, from the photo provided it appears to be an inline connector in the latch release control wire to allow it to be manually triggered. Ground would presumable be connected to the body of the car (there is a ground stud to the lower right of the fuse box).
It was always possible to do power the latch from the CJB by removing the big connector and powering it, but this way is easier.

[ edited to add ]

The white plastic thing you see on the left of the photo is where the body harness comes through the rear bulkhead, and is what I referred to as a "grommet" above. There is a matching one on the right hand side for the telematics harness which is the one you pry out to gain access to the emergency release handle with a hooked cable rod. (The carpet panel behind it can be pushed out of the way from the top down.)

Dumb question, but the internet is ambiguous on the topic: Is the squab the bit that you sit on or the bit that you rest your back on?

The squab is the bit you sit on. Jag's instruction is a bit confusing because that connector is behind the seat back, not the base, but the base needs to be removed to remove the back. The connector is directly behind where the small of your back would be if you sat in the rear right seat.
