The wiper switch is inside the steering column on those, and as luck (good luck) will have it, the handle with the switch just simply pulls out of the column, with the cruise control cable on it. The wire for the cruise control switch does indeed run inside the steering column, but I've found that it's fairly easy to replace as long as you remove the bracket that holds the steering column to the dash (two nuts that hold the column to the dash, and 4 bolts that hold the bracket to the column). Before you pull the old one out, disconnect the wire and tie a string around it - pull the wire through the column (with the string) and when you have it out, remove the string from it and tie it around the wire for the new unit. Use the string as a fishtape to pull the wire back down through the column.
You will:
Have to remove the steering wheel.
Remove the antitheft plate, using a special tool (but you can do it without the tool if you have lots of strength in your fingers, a pick-awl, and lots of patience).
Remove the turn signal switch, to gain access to the CC switch wire.
Disconnect the CC switch wire under the dash.
Pull handle out of steering column, then drawing wire out with it.
Installation is the reverse of removal, and with the string (as mentioned above) your job will be easier.
