Could I use a 10 gauge wire? New cars use 10 gauge for their high amp alternators.

Any help would be appreciated

Go w/the recommended gauge. That wire supplies all the power to the rest of the vehicle- it needs to be big.

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.
