[DML] BAFFLING ELECTRICAL QUESTION

[mike clemens <rmclemns@xxxxxxxxx>]

Okay, I came across something electrical this weekend
that has me totally baffled.  Maybe someone out there
can give me a good explanation.

If you follow the 5 wires from the windshield
wiper/washer switch on the steering column you will
find they connect to the intermittent wiper module
that is attached to a metal plate (boomerang shaped)
that is positioned above the steering column and
behind the binnacle.

The five wires going from the wiper switch and are all
attached to a 5-prong female plug that plugs into the
intermittent wiper module male plug.

Here's my question, if you look closely at the male
pins on the intermittent wiper module, you will note
that there are only 4 pins present, not 5.  I have
three different modules and all are missing the pin
that should connect to the brown/light green (NLG)
wire.  Coming out of the module, via the female
connector, all 5 wires are utilized.  I checked the
picture provided by DMC Houston of a module and it
also shows this pin missing.  Why is the brown/light
green wire from the wiper/washer stalk not connected
to anything??
