I have the Equus 9000-B in my '85 Westy ... hooked up to the negative
side of the coil for speed sensing.  It too is a vacuum type and I
installed a vacuum reservoir at the beginning.  It works perfectly and
has for two years now.

Apparently it is very similar to the Audiovox CCS 100.  I don't know
that the dip switch settings would be the same, though.

If you decide to go with the CV joint magnets and there is an option for
front or rear wheel drive ... choose front wheel drive.  The rear wheel
choice assumes magnets on a driveshaft whereas the front wheel drive
choice assumes magnets on CV joints.
