96 b4000 Crank Position Sensor

hey guys, does anyone have a schematic for the b4000 4.0L? I am trying to replace my roommates Crank Sensor for him but I can't seem to find it.

He's grabbing a Haynes manual today, but I wondered if anyone could give me some quick location information. Anyone who has done this before and has tips they would like to share, i'm all for it.

Thanks in advance.
