Electric fan install help.

The install is done and works perfect. I had to cut off the GM style connectors and add the Fords, glad I picked up that harness. Had to shorten the wires for my application, all expected and went easy. One thing I can't find in the directions was how to activate the hi and low speeds, I know they would on a ECM but nothing about how to run it stand alone. I'll be giving them a call tomorrow about it. Any ideas?
