The NF5 and F3 (NH3) PGM-II's are not the same, there's also pre-PGM F3/RS options. They may be the same.

The NF5 and NH3 (F3) PGM-II are definately plug and play with the mk2 mc18 loom if you want to go part way.
Pre PGM F3(RS) and PGM-II|(any) RC valve servo motors are not swappable, you will kill the CDI.
