My X has pneumatic door lock actuators from a 1990 VW Passat controlled by a Black Widow. I like pneumatic actuators – they have gentle action and I understand how they work. I installed a separate vacuum pump and pneumatic actuator for the rear trunk latch, controlled by the Black Widow trunk signal. The trunk lights stay on for three minutes after the trunk latch is released. The rear of the trunk got covered with fabric. Nothing is glued to the car should the next owner (after I am dead) want to bring the car back to original.
The latch’s lever was extended to three times original length to reduce needed force.
