You'll want to check the fuse first and foremost.
That one green wire should plug directly into the black "adjuster" disk (actually the choke coil cover).
i'll try to get a picture up asap.
P.S. As far as other wires controlling the choke, there may be one near the oil pressure sensor (the one near the oil filter) that may not allow the choke to turn on unless there is oil pressure, but:
a) i'm not sure
b) it doesn't matter right now
c) it's getting late and i'm getting sleepy......
