Under the dash there are two connectors, one yellow and one gray - right underneath the steering column. First though, disconnect your battery. Then let the power drain for 5 minutes. Then there are two covers on the back of the steering wheel. Pop those off and then you'll need a torx screwdriver to undo the bolts on each side. The airbag should come out now. Be careful with it. Then, theres a 17mm nut holding the wheel on. Loosen the nut (but dont take it off fully, and wiggle the wheel until it "pops" off), then remove the 17mm nut and wheel itself. Installation of the aftermarket wheel is reverse of what I just said.
