i see.  yes, it's certainly way more complicated than i was picturing. 
damn computers.  :-) i tried to correlate the above with the 595/speed
triple schematic at http://www.T5net.com/common/faq/Electrical/wiring.html,
but they don't match up at all.  oh well.

my bike and i really appreciate your help.  maybe i'll use a more
obviously switched wire to control my grip relay.  or i may wait until
i get my schematic in my manual, too.  it's warm enough to wait a week
or two for the grips.  :-)
