... remember that Bentley doesn't have a wiring diagram for the '83 model
... let me go and look at my car ... 

My car matches the Bentley on the Control Pressure Regulator ... Red/Wht and
Brn.
The jury is still out on the inj cooling fan, Bently says Red/Brn and Brn
... I thought I saw Red/Blk and Brn.  

As far as the vacuum hoses go, your car sounds just like mine ... which
matches the vacuum routing sticker on the hood and the diagram in the IST
documents ...

HTH!
