RL01 and RL02 cables have those funny connectors at both ends.  It
sounds like you haven't got the ribbon cable for the interface end
either; that would be a short 40-way ribbon with a Berg connector on
each end with one of the opposite-gender funny RL0x connectors plugged
into one of the Bergs.

I've never seen those connectors elsewhere, but on the inside of the
drive, they're 40-pin headers like a Berg connector, so you could, as a
last resort, use something else to get you going.

No, only early RL01s had brushes.  There's a field change order to
remove them, and AFAIR RL02s never had brushes at all.

It has to be connected and terminated before the fault light will go
off.

Look for the Pocket Service Guide -- that will give you what you need.
