I don't own a A132-4, but looking at
http://www.doepfer.de/A100_pictures/a-132-4.jpg I can see that there are
two black-and-grey capacitors direct aside the connector.

The grey stripe on the capacitor marks the negative side. Now check on
the solder side of the pcb to which end of the multipin connector the
corresponding negativ pin of the capacitor is connected to. This should
be the end of the connector with the red strip.
