Exclamation Wiring Century BN37 1,5hp spa motor

Hello all,

I am almost finished with all the connections related to wiring my Spa.
The Century pump I have really came with no directions. A simple schematic that makes no sense to me.

The pump is 115V and I have four wires coming from the control unit. Red, Black, White and Green. The green is a no brainer and it's on the ground plug.
Looking at the back of the pump there are three connections remaining. #2, which it say's is "Line". #3, which it say's is "High". And #4, which it say's is "Low.

After much googling, I can't find a wiring diagram at all for the back of this pump, and after all the time I have spent getting everything together, I don't want to burn anything up. :-)

I have read the black wire is for the "High" speed connection #3.
I have read the Red wire is for the "Slow" connection #4.
The only thing left is the "Line"connection. Is this for the white wire?

If anyone else has wired a 2 speed motor let me know this correct, beofore I fire it up.

Thanks in advance.

white would be your common wire, or # 2 in your diagram , ............... # 3 = high speed ........ # 4 = low speed
