Depends on the SD system you want to use.
I converted a 96 E350 van SD to MAF. I turned it into a 95 Stang harness. Very few pins to change and some adds like second O2 sensor and the injector wiring. Both used remote TFI,
You would need the pinouts of both the Ron Francis and the SD system and do a side by side compare. Then repin as needed.
