White is common, black is phase and the cap goes between black and grey.

I may be wrong however, the connections could be the other way around. You
use this at your own risk.

PS: The rationale is, that the larger resistance winding uses less current
and/or has thinner wire and should be connected to the cap. The lower R
one will have lower I^2R losses so it is most likely to go directly to the
mains phase.
