I bought the '89 Carat kit ;-) - it came to me this way, used.
Thanks for the instructions - I may be able to reverse-engineer this yet.
It would be nice to be able to drive at night again...

First and last letter of the color.
Didn't notice that Bentley used a different standard until after I
sent the message.
