So for some time, I've known the schematics for my 3.3l F225txrd show two charge coils,
each as "wye".
And that the subsequent 3.3l F250 is also "wye"
- although interestingly only one coil
but I only noticed today that the F150 introduced in 2004
has its coil in a "delta" form
Looking further, that when the 4.3l engines were introduced,
the "SHO" had two delta coils, but the 'offshore' two wye coils.
