"Shortly after man invented the wheel, he invented the trailer. Ever since then, he has been trying to figure out how to hook up the lights."
--Patrick McManus
The schematic I used appears in this article: hhrvresource.co...
Add a diode in line with each relay coil if you’re going to ground-switch your setup like I did. Otherwise, any trigger that's not powered on will supply ground to the relay coils through the tail light wiring (because the bulbs are just tiny wires to ground), and it'll click whether the switch is on or not. I'm not sure why this didn't occur to me sooner, but at least I got there in the end!
If you prefer quiet, here’s a schematic for a solid-state version that won’t drive you mad with clicking noises, along with an explanation of what's wrong with the usual converters.

You could also just buy a Hidden Hitch Powerline or similar, but where's the fun in that?
Whatever you end up doing, always check your lights before you tow!
