Thinking off the top of my head, I would say that the door switches are in
series rather than parallel. This way if a door is opened the circuit is
broken. Most door switches will create a ground or open circuit. No
voltage is used. If there are no pin switches look for a lever that is
pushed in when the door is closed. Usually has a black plastic piece
covering the metal lever. Check the door pillars for it. Tying it into the
door switches sounds like an excellent idea for the tailgate switch.

Great idea!
I have some of these switches, and they activate at 1" or less. Got double
stick tape on the backs too, with holes for screws of desired. Checked my
tailgate, and there are numerous mounting possibilities.
Wouldn't it also be easy to tie it into the "door ajar" circuit?
Except I just looked at the doors on my 01 QC, and I see no obvious switches
to tie into.
Must be a parallel circuit no? How does the system know when the door is
shut?
