'Have you ever wired a Santa Fe, or other Hyundai, to automatically lock
when placed in gear? I was wondering if there is a module, or wiring
idea to do this. With my very limited understanding of the wiring of my
beast, I would think that somehow sending a signal to the locking
solenoid would do the trick.'
REPLY: I had a 1995 Chrysler LeBaron GTS that did this whenever it would
go into 2nd gear of the auto transmission ; it locked all doors.
