If everything goes smoothly, you shouldn't have to pull the wheel. Under the dash, disconnect the 4 wire connecter for the turn signal/cruise stalk and securely tie a line to the portion that connects to the stalk. Remove the turn signal/cruise stalk by sharply pulling it from the column and carefully fishing the wiring and attached line through the steering column. When the stalk assembly is removed, attach the new switch wiring to the line that you just pulled through the column, pull the wiring through, and seat the cruise stalk into the column.
