adding cruise and keyless entry?>

[johnner2002es]

hello -- how hard is it to add cruise and keyless entry to my 2002 ES AWD Sport?  And I would only want the mfg. type units.  On our Honda CR-V keyless entry was a snap just had to buy the key fobs and program them.  Also Had a NEON (2001) that had a factory kit for cruise.  

whats involved with the MS and any idea on cost?

thanks
John
