So, I figured out that the reason I can’t find where the vacuum lines in the trunk connect to is because the entire vacuum pump, along with the foam covering and the tray it all goes in is missing on my car. No wonder the central locking was a no go. I’ll have to source all of that soon. I still can’t find the male multi plug connector for the infrared module that is disconnected. So weird that this stuff was all messed up but everything else on the car is in working order. Meh
