There is a very strong note in the RR (20V) documentation stating that
gold-plated and tinned connectors must _NOT_ be mixed under any
circumstances.  Somewhere in the archives there's an old post of mine
giving the correct part number for new gold-plated pins for the
connector so that a knock sensor with gold-plated pins can be attached.
