1969 Cuda Wiper Motor Connections for aftermarket motor

I have a stock variable set up. The variable resistor is in the switch, I hooked up an ohm meter and when you rotate it the value changes. I just need to identify the spade pinout on the new motor. if I had a 2 speed then it would be different. I have 4 wires from the switch and 4 spade terminals on the new motor. the switch controls the speed and when you push in it has an output for the washer. I see the connector for it on Classic industries but I don't want to pay 50 bucks. I can use 4 spade terminals individually, I just need to identify the pin out on the new motor. Red, Blue, Green and brown
