One of these wires is to tell the ECU when the automatic transmission
is in 1st gear.  Then the ECU keeps the boost lower in 1st.  The auto
transmission used in the 5000 Turbo cars was real wimpy at best.
I think the second wire is also auto transmission related, but I don't
remember exactly what it was for.
