Your best bet is to purchase a repair manual for your year and model. Readily available at your local parts house, book stores, or used even from amazon. Com or e-bay. Haynes or Chilton might also be available at your library.
Most CPS units I've seen simply screwed in and had an electrical connection that needed to be removed and then reinstalled. Not familiar with your vehicle tho.
Good luck and let us know how it goes. :)
