The brake controller connector is clipped to the back side of a panel located just to the right of the ignition key. You'll need to lower the panel and unclip the connector from the rear of the panel, then feed it down behind the panel so it exits out the bottom of the dash. I've edited a photo showing the location of the connector, and I've linked you to the install instructions for the # 3031-P.

I've also linked you to our Brake Controller FAQ article, which contains more information about brake controllers.
