Acura Alarm System - Wiring Diagrams?

Hello all,

I've come into ownership of a 2000 Acura Integra GS with an Acura alarm
system, which was installed at a dealership after the car's date
of purchase. The alarm system works fine, with the exception of the valet
button on the dash: I am not able to disarm the alarm by pressing the
button while attempting to start the car with the key, as I have been
instructed to do by a friend with a similar alarm system. I have checked
the switch and the wires for continuity and they seem to be fine, so I
suspect a wiring error or perhaps a failure of the alarm control unit.

So does anybody have a copy of the wiring diagrams or pinouts for this
alarm system, or know where I can get them, so that I can check the
system's wiring? Thanks in advance!
