Thanks so much for this helpful info and wiring diagram Bucko. It's a bit disappointing that Ford doesn't provide harnesses and both plug ins on the OEM hitch for the Bronco.
What I'm still wondering, is whether the built in resistors in the adaptor I sent the link for will work if I use the flat 4 to 7 blade converter dongle I found (other link).
Any thoughts on that? When I called "e-trailer" they told me the only way to address this issue using the 7 blade adapter I sent the link for, was to get a properly wired (with 12v power) 7 blade plug put into the Bronco. I'm hoping to find a way to avoid that...
BTW, the bike hitch rack does indeed use LED bulbs, so the issue is their low draw and not a problem with the wiring for the hitch plug.
