If you haven't already ordered your Cherokee, be sure you are ordering the correct 4WD transfer case option. For flat towing you will need the Active Drive II option.
Your current baseplate will not fit. The installation isn't real hard if you are a DIY'er. It does require removing the entire front facia but it is mostly held on with clips and small screws. The Blue Ox instructions are great. Be sure to get the diode wiring kit for the lights. Search the site here as I have posted the correct wire colors inside the driver side door sill for adding the diodes. There is a lot of time needed for the installation thus lots of labor costs to have it all done.
Good luck with your Cherokee. Its like a 2 minute hookup when it's done!
