Bill: Your diagram is clear in indicating the function and you wire colors match mine. I can not visually see the innards of my switch but I am suspect my white wire is not functioning properly. What it looks like, being the white wire connected to the brake switch, is the new power to the brake lights via through the signal switch. My brake lights do not come on with that configuration but I do get full turn signal function when pushing the brake pedal. I can get one tail light flashing with brakes on if I connect one side tail light wire directly into the brake switch. In other words, one tail light/brake light works properly and the other stays on solid with no flash if that side turn signal is activated with brakes on. For now , I'll wire to allow the left turn signal to function. I think signaling for left turns are more important than right turns.
