I have a trunk lock typically used in VW cars. The mechanical release switch works, but I want to use the electronic connection to open the lock.

The plug in question is a 4 pin VAG connector. I am not experienced with the world of car parts, has anyone worked with this before?

Superficial research suggests that the 4 pins are:

12V Ground Lock/unlock signal Status feedback

Though I haven't found out how to work with this yet. I have some limited experience in working with electronics and microcontrollers.

This lock seems ideal because it is free, sturdy, has a mechanical emergency release, and fits O rings and chain links easily.

Ideally I'd love to integrate this with some sort of deepthroat training device to only release the captive after performing the required training, or putting someone in timeout on a short leash. Both of these will require future work, first I wanna see if using this lock is feasible at all.

Thank you!
