Both of the Hopkins wiring adapters you referenced, parts # HM47083 and # 47549, will plug into a vehicle side 7-way socket and convert that connector format to a 6-way round-pin type. The main difference is that part # HM47083 includes a coiled cable that is 3-feet long when stretched fully while the # 47549 is just the adapter portion without the extension cable.

Another difference is pin configuration. Usually 6-way connectors use the center pin for the trailer's 12V power feed. This is how both adapters are wired, but the 47549 can be changed to allow a different function - trailer brakes - to be carried on that center pin. You can use either item if your trailer is wired with the center pin as 12V, but if your trailer is wired with its brake circuit on the center pin then the 47549 is the right part since you can configure it that way yourself.
