Ok, the slide switch is to select what type of PA microphone you use, it should be marked "M" for magnetic/dynamic and "C" for carbon/transistorized.
It says it will do 75 watts into an 11 ohm speaker, or 100 watts or more into two such speakers in parallel.
Connections are:
Pin 1 - +12Volts
Pin 2 - Ground
Pin 4 - Footswitch/horn relay
Pin 5 - Speaker
Pin 6 - Speaker
