Annoying Auto Locks

1994 VL,2 door,with those darned automatic door locks that lock when you start driving off.Have dealt with it all these years,but its very annoying.Is there a way to disable this feature? Is there a connection under the dash that can be pulled to disable the auto locks but maintain the power locks (manual override)? Hopefully something that doesnt involve massive surgery.

OK,I think I have tracked the culprit down thanks to a wiring diagram.There is a "Multi Function Alarm Module" that has 3 leads....#1 from vehicle speed sensor,#2 from park/neutral input (auto trans and this is manual),#3 to the door locks.So I guess if I disable the lead to the speed sensor,it will never know the car is moving and wont lock the doors.Now if I can just locate where they put that module.......
