On the Lokar kit that braided cable runs up to the eye on the bottom of the carb lever arm and is secured to a bracket that attaches to the back carb stud. That's all you see under the hood. I like the pedal mounted switch idea too. I'll have to spend some time in my parts books to see what I can find. There must be some kind of linkage and bracket that keeps it away from my big feet and controls the actuation so it doesn't kick own too soon.

Al 400s were electric. My '67 442 had a big ugly rotary switch at the rear of the Q-Jet.
