This is a good tutorial on stepping motors

I finally got around to actually setting up a stepper motor and

am :D

I am facing a problem thats probably pretty common. The datasheets
for my ST35 motor don't mention wire colour codes or step sequence.

I know I saw a web page that described how to determine the wiring
and step sequence for any unipolar motor - now I can't find it. I
did find one that partially explains it at:

http://redbaron.bishops.ntc.nf.ca/intsys1215/vbreferences/vb-
webpage/stepper.htm

So I know which ones are center taps and can group two sets of three
wires - but I don't know which ones are for coil 1, 2 etc.

I've been fumbling with different step sequences and mixing and
matching the wires (seems to work almost no matter what I do!). How
can I determine the proper step sequence etc?

P.S. I did email the manufacturer but I'm not holding my breath on
that...
