You will need to wire the L terminal to a source of switched ignition-on power through the resistor. Connect the S terminal to the main power lead at the same junction where the alternator output lead connects to the main power lead that goes to the battery. That would normally be a couple feet away from the alternator. The F terminal is not used, so that plug you show in your fingers is not the right one, since it has F and L wires.
Here is a write up about using the CS alternators.
