I had the 'Tow Prep Package' on my 2012 R/T Rallye with all intentions of towing later. Recently went out and bought a Curt Hitch and fitted it myself along with the supplied harness. The harness fitting instructions were all there, remove the bumber (which you don't have to do), plug in harness, replace bumber (skipped this of course) and try em out with ya trailer. reasonably easy to do.
Found the trailer I wanted and went to pick it up from Home Depot.....no bloody lights!!!
Well, thanks guys for all the posts on here cuz now I know the Dealer has to reflash my ECU.....dealer has confirmed this! Just hope they are not gonna charge me!!!
