The harness you select will depend on if you have LED tail-lights or not, and took me (curt harness) maybe 3 hours to install.
FYI, if you buy the factory hitch (no better than the Curt), don't follow it's instructions and remove the bumper to install, it's completely unnecessary to do that.
Or draw tight 76527. it sticks farther out to help clear the spare tire And has a little higher capacity. But I think it looks a bit funny.
you can watch videos at the following link to compare, but cheaper on amazon https://www.etrailer.com/s.aspx?qry=Bronco+hitch&ymm=1
so that's drawtight 76527 or curt 13493
that link also shows the two wiring harnesses led vs non. Get the right one. cheaper at Amazon.
Led curt 56468 curt
non led curt 56471.
and here is the install video...
but.... on the hitch don't use lock washers, bad idea and the maker includes proper bolts now
on the wiring harness. Don't cut the green wire. he bought wrong harness and modified it.
I got the Curt one for my Basesquatch. Installed it in 15 minutes. I use it for a bike rack only so I do not have the wiring plug harness yet. It works perfectly for the bike rack.
