I can't seem to find a concrete answers to this, but long story short, I have a race coming up this weekend and I live on an island where no auto parts store has an alternator is stock, and most likely would not arrive on time anyways. I do however have a few used NB alternators on hand that I'm considering to use. I know the NA ones have a built in regulator and the NB's are controlled via ECU, and I also know the MS3pro allows you to regulate the voltage as well.

My question is, is it a matter of just swapping the NB alternator in and changing a few settings in tunerstudio? Or will I have to splice a few wires to correct the outputs? As a temporary solution I'd rather not splice anything and just miss the race, but if I can just hot swap and change a few settings, I can make my race.

On NAs, the small white/green wire is fused power, the white/black wire is the ground light for the charge light to turn it on/off when batt V is below/above 12 volts or whatever the regulator's set to.

On NB2s, the grey wire goes to 4t, the grey/red wire goes to 3M. According to Link's wiring pinout, the grey/red wire is your alt control wire, looks like they don't utilize 4T, they just call it "alt voltage".

So wire the grey/red to an output on your MS that you can select in the "control output" drop down menu of the alt control page. Download a NB2 basemap to get the rest of the settings.
