CONGRATULATIONS......EXCELLENT ADAPTATION AND CLEAN LOOKING INSTALLATION.
A few questions if I may .....
1. When energized open, upon shutdown, will it close automatically like the vacuum operated unit, via the under dash mounted relay and spring? I assume that the actuator must be powered ON to open.
2. The origional dash mounted air grabber "switch" is really a valve, directing the vacuum signal to/from the actuator and solenoid. Is your air grabber control device a D.P.D.T switch, that reverses the polarity of the actuator's motor?
3. Does the actuator have its own internal end of travel limit switches to stop the open/close action or does the driver place the open/close switch in an "off" position when the actuator is open or retracted ?
4. Are you going to market the individual pieces and parts? Where can I purchase the linear actuator?
Again... Great effort
