> It seems like the connection has more than 4 pins - but it's in pretty rough shape. Anyone know what kind of connection this is?
Looks like a 7/8 flat trailer connector, the 8th socket is likely dead as it's not used in North America. The 4 with the 3 sockets and 1 pin will likely be your standard 4 wire trailer connection. The other 4 are most likely for reverse, brake and +12 VDC with the 8th one being dead.
With how beat up this connector looks, dragged and corroded, I would have it replaced with a sealed 4 and 7 pin housing, EX https://www.amazon.com/Hopkins-Towing-Solutions-47185-Multi-Tow/dp/B0002Q80GS, the flat 4 and round 7 are the North American standards used.
Since this the first time pulling any major weight have the receiver inspected to make sure that none of the bolts or supports are rusted out.
We actually bought a 13 pin and 7 blade housing and did it ourselves because nobody makes a harness like that.

We didn't use the 4 pin on the second link. Just cut it off. Assuming you haven't already wired up the brake controller, you need to tap into the red and black wire for the brake pedal and recommend a posi tap for that.
