Wiring a retrofit soft start blower into a Ruud...

Question

I need help wiring a new soft-start motor/blower into my gas pack. I have two black wires from the old belt-drive motor but the wiring schematic shows three, a black, orange and red. I hooked these two wires into the Low and Medium terminals on the new motor and got some bad smoke. I'm using the wiring drawing no. 90-23596-01 Rev. 4.
