You have (-) door trigger so the cathode band is facing the door triggers. You may have to double isolate the wires with two diodes ( use two 1 amp diodes ). Aswell you havet o grab each door separately and diode isolate each door wire not just from one door pin.

Doesn't really matter, as long as it's grounding you will have a signal. The problem your stating is that it falses with a door trigger notification from the alarm. Make sure that the trunk trigger is sending a (-) pulse ONLY when the lid is open. What you can also do is disconnect one of the triggers for a while until the alarm falses again. The n you will know which one it is.... the hatch or the doors.
