I like your idea, Rob.  However, a word of caution, if I may.  Nylon
locking tie straps - also called tie wraps - vary in both thickness, width,
and application.  That is to say, if you use a thin, white or clear tie
wrap in the "harsh" undercarriage environment of a Vanagon, it could
deteriorate rapidly, as it is ment for indoor applications.  There is also
the chance that a thinner tie wrap could cut the rubber boot.  You would
need to find a black tie wrap, as these are considered more suitable for
outdoor applications.  Too, Thomas & Betts, Burndy, and Panduit make a
metal tie wrap that may be more suitable for the application.  If memory
serves, you can see them in a Newark Electronics catalog (I think the
catalog's on line) or at a Home Depot type store.
