Greetings listees!

I'm in the process of rewiring the 14 pin connecter in my 83.5
wasserwesty to install the new, later-model, tach-equipped instrument
cluster I acquired from Chris.  I've been following the circular wiring
schematic I found in the archives.  I have a couple of questions for
those more knowledgeable or better able to decipher Bentley than me:

1) The red/white wire that used to connect to pin 12 is for what? And
should it really be left disconnected???

2) There was no blue/green wire attached to pin 11 when I started moving
wires around.  According to the Bentley wiring schematic this is for the
OX SNSR ELAP MILE SW or something like that..  I seem to remember
something about only Californian vans having these, is this true?

Thanks for any help or clarification you can give me.
