What you've advised is not working on my vehicle, which is my wife's old car). My wife now has an '06 Taurus and that answer works fine for that vehicle (in fact it is even in the owners manual). If you know of some way I can disable the automatic locks (i.e. cutting or disconnecting wires, etc.) that would be acceptable. I don't care if it never works again. Thanks. ...........Charles Hinton
Since this procedure does not work you then need to go to your local dealership and pay them to change the programmable parameters in the central security module to turn off auto lock, there is not just a wire you can cut to disable it unless you want to disable all power locks.
To divert back to all manual door locks you will need to try this, depin the yellow black wire from the module at the base of the right hand A pillar above the passengers right foot. Do this with one window down just in case you cant get in the vehicle. I have never tried to disable this and am somewhat worried the locks may not move manually once the doors are closed. See the diagram below with the wire your disconnecting in the lower left corner.
