@rubeng1128 In this version I am using a relay but the new version uses a couple of transistors. The control for unlock/lock the doors on a mercedes benz 190 just requires a 12V to start the vacuum pump and open the doors and a GND to invert the vacuum pump and unlock the doors.
what are you using to trigger the doors to unlock is it a relay or an alarm system
