1 wire alternator 170 AMP

[roll_the_dice]

OK, I am connecting my alternator and it is easier (less obtrusive) to wire it straight to the positive lead on the battery. I assume that is fine?

Also, I am using an AAW wiring kit and the alternator cable they sent is a 6 or 8 gauge wire with a fusible link. My alternator is 170 AMP that I got with my vintage air front runner system. I am worried the wire is not large enough to carry the current. Should I go with a 4 gauge for this alternator? And lastly your thoughts on a fusible link for the alternator? I know our trucks didn't have them originally, but this alternator is much larger than OEM also. Thanks
