Claim:
1. A door latch activator system for a trailer or truck body coupled to a door latch, the system comprising: a plunger installed in a path of the door latch such that when the door latch is moved to a latched position, the door latch is configured to push the plunger, the plunger including a spring; a switch configurable into one of an open or closed position by the plunger; and a pneumatic valve configured to control flow of pressurized air through the pneumatic valve depending on the position of the switch, wherein the plunger is moved toward the switch by the door latch to engage the switch when the door latch is in the latched position, which triggers the switch to activate the pneumatic valve to allow the pressurized air to flow through the pneumatic valve, and wherein the plunger is moved away from the switch by the spring when opening the door latch, which deactivates the pneumatic valve to interrupt the pressurized air flow through the pneumatic valve.
