Part # FT1Z15A416A
I’ll try and keep this short, no need for a full write up. I used the installation Manual provided by @bjbena for each and every step.

First, this is definitely a doozy. Unless you’re confident with wiring I would not recommend diy-ing this. The wires are 20 or 22 gauge (I’m not positive) and very prone to damaging. So unless your an idiot like me and willing to damage essential functions than I would honestly just get the tekonsha or Curt or U-Haul plug and play harnesses lol.
Where the manual says to splice into the oem wiring (image #11) just wasn’t realistic due to it being a huge bundle of wires with zero play to solder and strip back. So I opted to splice in right before the wires entered the grommet going into the tail light housing.
I did confirm the wiring the manual references coincided with the actual wiring my vehicle had, with a probe into the taillight plug.
When removing the plastics be patient and take your time. Any time your about to hulk out stop and assess what might be catching.
Maybe I couldnt figure it out but I was unable to completely remove the cargo area plastics, from what I could tell I would have had to remove the rear seats to free them so I just worked with the space I had. Also, the manual states it but I’m gonna state it again
Disconnect your ground at battery! The lower A pillar plastics and B pillar plastics are close to air bag components. I think anyways. Lol
I am not a professional, I worked at a tractor dealership soldering telematic kits and various soldering for a few months.
I’m more than happy to answer any questions and provide any tips but honestly, just get a professional. This took me 4.5 hours. 30 mins was confirming the wiring on my vehicle and the wiring in the manual was the same. 30 mins was just staring at the oem wires petrified and assessing how I was gonna do it all without damaging anything.
Be easy on me. If anything looks shoddy it’s not out of laziness, I did everything as close to the book as I knew how/could.
