When you suggest Trunk sensor, what do you mean ???
Grab handle, boot release switches ???? To replace this, as I did the complete boot requires stripping down including the rear panel
On the boot, on the carpet section, by the grab handles, there x2 (each side) torq screws, remove all four, then pull, pry the carpet section, it's held on with pop studs
Moving to the lights, on the outer edge of the boot, there's a plastic outer cover with three plastic studs, remove the studs then careful work off the plastic trim, being careful as it easily broken, there is mounting tabs.
With these off, access to two/three 10mm nuts will allow removal of the lamp assembly
