As I recall I got mine at Ruralking.  I recall it's a 1.25" x 2" adapter.  This accepts a Standard 2" Reese Hitch. They do make a 1.25" to Ball adapter.  Curt makes several Styles.  I use a "Zero"  drop on mine because it lines up with various Carts/implements.

Rick:  I can't say as to a Comparison to a Rigid.  I haven't got a Rigid. As to Installation no it is not Plug and play.  The Kit comes with a Relay and the Accessory switch on the dash  has two position one(Up)  is for a front plug, the Down position is for the rear plug. I used the wires going to the plug (tucked up above the Right front wheel for the "trigger for the relay. it was about a 3hr job owing to me moving slow because of recent back surgery.  The plug is a female (2 conductor) plug.  I would have liked to bought the opposing male but no one at Autozone, NAPA, O'Reilley's had any clue as to the type of plug.  The Hisun Customer Support was equally unconcerned.

I bought the Rural King Branded version the 750 EPS.  I added this from Amazon:  https://www.amazon.com/gp/product/B01M2AF4JE/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1

On my 2021 750 EPS there (4) #16awg  Wires on the back of the "ACCT" Switch from Top to Bottom as if viewed from the windshield looking the vehicle. They are (top to bottom:

Or/Rd - 12vdc from Fuse 15 panel under front hood/cowling

Yel/Red - switched (above 12vdc) to Rear Driver Side Gray Plug

Blue/Brn - 12vdc from Fuse 15 panel under front hood/cowling

Red/Brn - switched (above 12vdc) Passenger Side Fender Well Gray Plug 

In my case I used the switched  red/Brn to trigger a Relay to Drive a 52in Curved Light Bar. I plan on using the Rear ACCY Plug to drive (2) work lights over the Bed pointing to rear.  For those looking for the "elusive" Gray Plug it looks like the photo...EXCEPT there is a water proof pug blanking it off.  Mine was Black

Following this thread.  I have a 2022 750 EPS and want to use the ACCY switch for a "Back-up" light Bar and the other set of Contacts for an Over Windshield  Light Bar.
