1 off, 2 on = 3rd
1 off, 2 off = 4th
Further notes from the reading mentioned above...

To diagnose which wire is Sol1, Sol2, or TCC...
Engine running, shifter in Drive:
12V to Sol1 = trans shifts to 1st, and vehicle moves easily with throttle
12V to Sol2 = vehicle accelerates sluggishly
12V to TCC = engine should stall

Sol2 malfunction: Shifter in "L" - trans will never shift out of first gear.
Sol2 malfunction: Shifter in "2" - trans starts in 1st and eventually shifts to 3rd
Sol2 malfunction: Shifter in "D" - trans starts in 1st and eventually shifts to O/D.
