Most peeps will do the big three wiring upgrade which is larger cabling:
Alternator to battery positive;
Engine to chassis ground;
Battery - to chassis ground.
Most people don't do the wiring upgrade. Even though you're going from a 100 amp to a 145 amp alternator, it's doubtful it'll reach 145 amps output as the car will only draw what it needs-unless you've added some sort of heavy electrical load such as a big stereo system. The main reason to do the alternator upgrade is because the larger unit has more output at lower RPM's.
