you can re-flash the PCM to remove the 4r70w transmission controls
I have seen evidence that a 1996 Bronco and F-150 was available with a 5 speed and the 5.0L (Gt-40) so this computer and wiring MAY work for you, I have never seen this setup in person, in 96 only 5.0l and 5.8L with autos here in CO
