I have learned how to program a keyless entry fob for my 1996 F350 diesel and want to share my findings.

1, locate the control module under the dash. mine was located just under the dash kinda between the accelorator pedal and trans hump in front of the door chime module (if your chime is hooked up, follow the sound).
2, There is a 2 pin grey conector taped on to the wiring harness for the controle module.
3, Make sure key is off (door does not have to be closed)(it also helps to have all the fobs laying on the floor) Jump the two pins. turn ignition key to the on/run position. Locks will cycle. press lock or unlock button (does not matter which), locks will cycle for each fob.
4, After all fobs have been cycled, turn ignition off. Locks will cycle one last time. Unhook jumper. Enjoy.

Now my wifes '97 mountianeer and my '96 dually use the same remotes.
