Stoked

I have a 2007 with the factory tow package. The 7 pin/4 pin combo on the rear hitch needs to be replaced due to damage, but I am coming up blank. What I am finding online that is supposed to be "plug and play" with my truck doesn't look like what I have. The factory harness has a large, rectangular plug, a smaller, round plug, and a pigtail for a ground. I removed the harness and found a part number, but I come up blank when I Google. I got a hit for a part number that is close, but the plugs look different and it says it's for a Superduty.

Has anyone else come across this or have some thoughts? Maybe a cross-reference for another part number?
