rewire passing lights
Doing as shown in the diagram will make the passing lamps work when the ignition is on and no the accessory switch does not have to be on. If you end up needing the switch on to have the lights work you tied into the wrong accessory wire ;-)

If you follow the wiring diagram above, you will be splicing into the wire that feeds the accessory switch, so that switch will have no effect on the spots.

since you are wiring the hot side prior to the accessory switch, the lights would come on when you turn on the ignition. If you are not using your accessory switch for another any other purpose, I would think you could wire it so the lights come on by using the switch. If I am wrong, please someone chime in.

The passing lamps do come on when the ignition is in Accessory, just need to turn them off if your bike is off listening to music or whatever.
I used that same diagram.....results are great or bright I should say.

Psychic energy! I was thinking about this mod right as this thread was going. If you search under 'passing lights' there's a bunch of threads, but they all seem to boil down to the diagram and using a shop manual to implement the diagram.
Here's something from Cap'n buzzcut to have the passing lights come on only with the highbeams, activated by the highbeam switch. This is the mod that makes the most sense to me:
Well, I had already done this mod on my RK, but what I don't like about it is that if you leave the toggle switch on and turn your ignition switch to acc, the passing lights are still on. That's not really a big deal, but it's annoying if you turn off the bike and switch to acc mode regularly, like to power LED engine lights or a radio.
Here's what I did: Instead of the re-connecting the yellow passing lights lead to the acc circuit, find the blue wire inside the nacelle that leads to the left handlebar switches and connect it to that. That wire feeds power to the high/low beam switch. In stock form, this circuit provides power to the headlight and your passing lights, so all you're adding is the extra high-beam load, which I'll bet is the way it was wired in previous years anyway.
