The bigger alternator is a "drop-in" upgrade. You will need to transfer pulley from old alternator but that's it. I did not have to shim anything, everything lined up perfectly. Unbolt old alternator, fit new alternator, wire up connections and you're good to go.
To get the full benefits of all this new power you are supposed to build a heavier gauge wiring harness for the alternator to distribution block. Since I only went to 120A, not 150A, I elected to keep my stock harness for now. Still manages to put out 13.5V at idle with everything on (headlights, fog lights, stereo, 4 way flashers, defroster, wiper, etc). At some point I will upgrade to heavier gauge wiring. It was a luxury I didn't have time for when I did the swap.
