DC controller repair kit

I ordered the HPIIIP DC controller repair kit. the video seems to deal with replacing the Density controller and the scanner assembly. Nothing about the DC controller. If 'DC controller' is short for Density controller, then the part I got looks nothing like that. it looks more like a mother board - like the one sitting under the formatter board assembly on top that everything is plugged into. what am I missing?
