TPS A Dk green (TPS return) goes to D1 on the DFI connector
TPS B lt blue (TPS signal) goes to C1
TPS C yellow (+5V ref) goes to D5

All the DFI ECM's have this capability. I think it's off the global
variables menu... You either ground or power pin B9 (nitrous enable) and
then the output is B11 (nitrous solenoid)

If the software isn't copyrighted, I can email a copy, since you need
their little black box anyways. The $200 for CALMAP and the cable is
worth it if you plan on doing some tuning. HTH
