Could someone look at these and try to put into words where the
transformer wires-- 2 black & a green-- go?

If you want the transformer to power up when the blower is on, connect it to
the white and black wires where the diagram shows the blower, unless you're
using the medium speed, then use the white and blue


Thanks-- I didn't think that was a choice *I* made. I thought the
furnace chose the speed & I was looking for something to connect to
before it made that choice. I'll have another read through the
literature to see what it says about the two speeds.

Thanks-
