The pin in question was E5. Range switch C. I need a better proofreader. :(
That matches the manual trans wiring diagrams.On the '7747 to '427 PCM conversions I've done, I covered the P/N wire with heat shrink tubing and zipped tied the P/N wire to the harness.
Those diagrams also show two signals from the DRAC. One is VSS and one is trans speed. The "possible symptom" for a faulty trans speed signal on F13 is "fuel cut." I have a 4k ppm VSS signal to supply. I do not have a 40 pulse/revolution trans speed signal.
