Yeah, I second that very much.
Don't EVER assume anything when it comes to wiring configurations, I did that with my iBook 12 to 14 inch mod. The battery connector is moved, and I assumed that the wiring order (and battery voltage) would be the same. Poof, there goes my logic board. frown

Best thing you could do is probe a USB Port and see what the active voltages are on the data lines. That way you can double check them on the iBook connector. And through process of elimination, figure out if it's okay. Obviously 5+ and G would be a 5V reading, I believe the data lines were 3v last time I checked, but certainly don't quote me.
