Between the manuals, they list high gear, 3rd/2nd gear
inputs, and the 747 has a high gear input. My 82 Z28 has a '84 T-5 5speed
with no connections other than backup light. What function does this
connection relate to(anything other than converter?)and should I leave it
disconnected or tie it to something else?
I thinks your comparing auto tranny 747 to manual xfire,
try manual 747 to manual xfire.
