I don't know exactly what you mean, but I might have a solution, quite low-cost and reliable (when done wel). I installed this system in a Volkswagen Golf (Rabbit in the US) for a friend who wanted to convert his fogs into extra brakes (so he would have 4 brakes), without losing the fogs... This actually isn't that hard: all I did was install a couple of heavy Diodes that could easily work about 5 Amps (that's the current for a 21Watts bulb + a safety-margin) I simply put the diode between both plusses of Brake and Fog, with the Cathode connected to the Fog-side. Since a Diode is comparable to an electronic "one-way-valve" it allows current to run to both brake-lights, when power is switched to the fog-light only one bulb (the inner- or the outer-one, that's your choice) gets current because of the diode! When I firts put this together I forgot ONE thing: a Diode has a voltage-drop of about 0.7Volts; so the "non-fog"-brake-light was a bit less bright... This was easily solved by adding an extra Diode in the Brake-light-line, so both bulbs would get the same voltage again. I've made up a couple of scetches to explain what I mean, I'll put them in the Vault for anyone who's interested.
