This is a feature of an alarm system. You can't defeat it unless you remove
it.  The manual seems pretty complete to me, just like the one that came
with the Avital unit I installed last year.  Just map the colors on page
five with the Vanagon wiring diagram.
http://www.directed.com/guides/manuals/ig/valet/N711T.pdf   You won't use
all the wires provided in a Vanagon installation, and this sounds like a
professional installation.  PO probably paid $500 to $700 to have it
installed.

If you don't need the alarm just clip the wire to the siren and use it as a
door lock controller and ignition cut out just in case.

 . . . . .the only thing that bothers me is that the door locks operate
about 3 seconds after ignition key operation  and I have not found a way to
defeat that yet . . .
