I have been looking for it for about a half hour now, I can tell you the PCM sees the input at IAC Mode Word #2, L4E86 bit 1.

AAHHHH. I would test it if I had a way. What does the switch put through on this wire?

Might try this, and just uncheck TCC only. But you would need to set up something for the kickdown. I think dave w had something figured out in the .bin to use a PCM output to kickdown. Try a search.
