So I bought a 125 amp alternator for my 92 4runner with the 3.0v6. What do I need to do to the wiring before I install this alternator? I was thinking of increasing the power wire size and ground wire? Not sure what size to go to? And what other wires should I upgrade. I don't have a winch or duel battery setup at this time, but would like to add these in the future. Any info or help is greatly appreciated.
