Help with small lifting motor wiring? Where does the other end of this resistor go?

[static zap]

.....Curious about the up/down switch as I don't see how you can achieve up/off/down (which I'm assuming is the operation) with only two wires.

Me too , look closely at switch .

Resistor a bit small to discharge cap , but reduce speed in one direction ?

It's not using only 2 wires, the OP had missed out a Blue wire in his original diagram.

If it's a stepper motor then I can't help, but if it's a single phase induction motor I have a thought, for what it's worth.
I think the R was in series with the C and they are used to create the phase shift in the 2nd motor winding needed to start it. (It looks like a diy mod - not happy ...). So the floating R wire should be attached to the top brown wire that goes to the switch. I've attached a diagram of what I've in mind. Please remember this is a 230V motor and the wiring is clearly in a distressed state and not suitable for use, in my humble opinion.

1. see: Permanent Split-Capacitor Motors - http://www.industrial-electronics.com/AC-DC-motors/54_Permanent-Split-Capacitor-Motors.html for a ditty on Permanent split Capacitor motor (single value capacitor - ie just one capacitor for both start and run.)

2. see: What is a Capacitor Start Capacitor Run Motor? - its Phasor Diagram & Characteristics - Circuit Globe - http://circuitglobe.com/capacitor-start-capacitor-run-motor.html for a PSCM -2 value capacitor - ie: two capacitors in parallel for starting and then one switched out of circuit once running at operating speed).

Just revealing "GUT" feeling part of Fault finding process for others to see ...

At times you lead your self up the garden path !

it must be to power, as the capacitor must have a feed, I can only think its to smooth the supply ,

AC Motor in this case , it's all about creating 2 ac signals,
one out of phase to other.
To run the 2 coils in the motor .
(as per diagrams provided by others)
Less smoothing, more delaying by a CR network .
