Ken,
I agree for turns, but that jumper is the brake circuit which appears to jumper both sides together. If so, then when he jumpers power to the brake switch lead then the bright filaments in both sides should light. What I cannot figure out, without an internal schematic of that turn signal unit, is the case where you press the brake, and at the same time have one turn signal "on", in which case both rear lamps should be "bright", with one flashing for turn. I don't see how that is accomplished with this switch.
