Is there a truck button for a 1992 xjs v12 jaguar?

The 1992 Jaguar XJS V12 does not have a dedicated "truck button." Instead, it features a traditional trunk release mechanism, typically accessed via a lever inside the car or by using the key in the trunk lock. If you're looking for a way to open the trunk remotely, you may need to check if the car is equipped with any aftermarket remote access systems.
