End of autumn greetings,

I'm re-installing the kitchen in my '84 Westy.
Today's question is: Could someone provide me the top-to-bottom order
of wires that plug into the side of the water tank. They are for level
sensing. There are four wires: white, black, green, and yellow. I
wrote the order down when I removed them last year. Hmmm, wonder where
that scrap of paper is?
Also, I'm in need of the water tank drain cap. If anyone has an extra
or knows a quick and easy source for replacement, that would be great.

Thanks.

Kevin
