St is for start. If you are useing the key turn to start you will use that term. It uses a purple 12 gauge wire to the starter sel.
Hook all your acessory items to the acc. term. It is powered when ever the key is on except it shuts them off when in the start position to take the load off the bat. Like the radio, heater, & turn signals.
