Connect the pin in question through a 2k4 or 1kOhm resistor to GND, than release or connect (through the resistor) to +5V (eg. EC36/29 suitable for this) and you will see the relevant mcp3208 channel change accordingly.
"Trial and error" is usually not the recommended method (recommended: following the actual pinout, any customizations marked on paper), but in this case it is OK. The resistor is important (especially when checking arbitrary EC18 pins), because if you connect to an output, the resistor limits current to smaller than 5mA (eg. the +5V regulator or a digital output, especially stepper outputs could be damaged if connected directly without the resistor).
