THe service manual doesn't actually show the connector, it just numbers
the 2 connections '1' and '2'. However, it's clear from the schematic
that the +ve side goes to the power switch (a single pole device), so it
should be easy to check which this is with an ohmmeter. The -ve
connection goes to the systgem 0V rail, which should also be easy to
find. I _think_, from looking at the PCB overlay, that the centre is
-ve, but check this before blowing up the machine!
