type F: one-wire system (cut to lock, ground to unlock)
This type of door lock system usually requires a negative pulse
to unlock, and cutting the wire to lock the door. (With some
vehicles, these are reversed.) It is found in the late-model Nissan
Sentras, some Nissan 240SX, Nissan 300ZX 1992 and later. It is
also found in some Mazda MPV's.
