No, the plugs are not compatible. You'll need to get an electrical connector for the Q45 and then you need to rewire a couple things for it to work. No, not all FFIMs accept the Q45 TB... there are several popular throttle bodies used on FFIMs and you'll need to choose the TB accordingly. The Q45 is probably the post popular choice though, but make sure before buying.
The wiring details have been posted here and at supramania and supraforums a few times in the past. It shouldn't be too difficult to find with a little searching.
