You can go straight from the alternator to the battery instead of going to the starter where the positive cable from the battery attaches. Are they telling you to use both (talking about the "second wire" reference)? For that matter you could use a remote solenoid and get rid of the positive battery cable to the starter that's always hot.
They are telling me to use both wires or because the battery is behind the passenger 's seat and the the alti. is on the drivers side the guy told me to use a even larger cable because of the length of the cable
