remove that little plastic cover behind the shifter where the ebrake sits should be 2 holes and line them up with the 2 screw holes should screw down firmly you might need longer screws though and some little spacers to fill the gap between the plastic and the tunnel. it wont line up with the center piece on the dash so your going to want to try and find another ef center dash piece and cut it up to make a filler piece

this is mine i still need to make the filler pice for it but its fastened well and doesnt move at all
hope this helps
