Well, I checked the issue again, and as I thought, there's nowhere I can plug the wire to. The latch only has the mechanical part, I searched the forum and found how the sensor looks like, the plastic part attached to the latch, and my car doesn't have such sensor, only the latch itself. I'm wondering if it is worth it to try to get the part since my car acts normal. Haven't had any issues with the alarm of similar problems, it's just that it kind of annoys me to know my car is "incomplete".

Thank you for your help, and as always, any input/opinion is welcomed.
