Hey Doug the plugs are for plumbing hoses and fittings for the cooler. Look for the extra wires on the left of the diff for the pump and the bracket to the right of the diff for the pump. Scoop goes in the center ahead of the crossmember with the cooler. Let me know if you want help setting that up "while you're right there". I would vent it off the back cover but don't do it in line with rotating parts and install a good baffle on the inside or it shoots slung
oil up the tube.
