This is where the hole for the stalk is drilled. It puts it closer to the dash so your knee won't hit it and snap it off !
This cover just snaps off below the steering wheel, and will look like this. You can move it farther out like the instructions.
But I have seen a lot of people hit them with their knees and damage them.
After drilling the hole, put the wires thru, tighten the nut to secure the stalk.
Install them into the white and black connector as per instructions.
Route the wires in a safe route. Secure with tie straps.
