I recently bought a A.O. Smith 2 HP Square Flange 56Y Dual Speed Full Rate Motor - B2984 

and installed it, it runs great.  My only problem is that I connected the wires exactly how the old ones were connected, but now the low speed and high speed are reversed.  It runs on low speed when I choose high, and it runs on high speed when I choose low.  Is there a way to switch that easily?  The power wires don't have enough extra length for me to switch the two red ones (I'm assuming that the red ones control the high/low power).  There's the green ground, one black, and 2 red wires.
