That is an interesting unit and would do the trick.

Well, yes I have. It's been a few years, though.
I just want the third brake light back on my Jeep.
Then again, I'm looking for a cheap Hypercharger for my Harley and
can't find one of them, either(which surprises me as much as people
bash*them* too).

Re: Trailer wiring question
You bought a device that is looking for a system that has a turn signal
separate from the brake lights. You need a device that connects to all of
the wires, then can isolate via diodes the turn indicators and use the
signal to the brake lights.
