1986 FWD 4-door Corolla carb solonoid question

Which of the two solonoids is which? The factory manual gives
contradictory information but mostly shows the 1-wire solonoid being
for the primary barrel, the 2-wire solonoid for the secondary barrel.
However the wiring diagram has the colors wrong: The 1-wire is
supposed to have a black-yellow wire but actually has a white-black
one. The 2-wire solonoid is supposed to have black-yellow and green
wires but actually has a black wire and a white-black wire.

Also is the 2-wire solonoid supposed to leak a little even when closed?
