Upfitter Switch (9L7) Service Parts Retrofit Kits

It has recently discovered that there is a problem with the list of contents for the Upfitter SERVICE PARTS retrofit switch “kits” for vehicles that were not ordered or built with the 9L7 option. The discrepancy has been corrected and new part numbers are being generated.  The kits are temporarily on “hold” until they can be properly assembled with all the components required to perform the retrofit.  Stay tune for updates coming soon.  This situation does impact the kits that are shipped with the vehicle when the 9L7 option was ordered.
