When getting the trailer tow package on a grand caravan sxt, does it come with the 4 prong or the 7 prong?

I am just annoyed because I said I needed what I had on my 2012 van and when I got my 2017 it was the 4 pin. I said that it was not the same and was told ‘this is how it’s done now’. Which it is not. We recently bought a camping trailer and can’t even tow it because I need the 7 pin. I am just annoyed because I said I needed what I had on my 2012 van and when I got my 2017 it was the 4 pin.

I sympathise; the regulations around the construction and use of trailers grow almost annually and have become very complex. Ordinary people depend on the guidance of experts and should not be fobbed off by a salesperson who should be expert but clearly is not.

With the best will in the world the essential lighting cannot be driven via a 4-pin setup if a hard wired ground is needed (best). These days for added safety the tail lights have separate circuits making a 7-pin setup necessary.
