ATU P6/J7 alignment

[Buck - k4ia]

It's the old P6/J7 question again.  I found some references in the  archives
but they just say "Wow, be careful" or  "I once was lost but  now I'm saved."
without actually telling how it goes.
 
So can someone help me get this straight?
 
If I wire J7 as shown on page 10 of the manual and install P6 so the  locking
tab is to the front of the radio, the braid ends up in the connector  that is
closest to the edge of the radio.  But, it looks like the ground  side is the
one closest to the center of the radio not the edge.  In other  words, either
the drawing on page 10 is backwards or the locking tab has to be  to the back
of the radio or
 
I JUST DON'T GET IT!
 
Comments?

? Page 10 shows ground on the left of J7 when viewing it from the "non-locking tab" side. If P6 is installed with the tab toward the front of the K2, the ground will end up on the right, toward the edge.

Buck,

No matter how you interpret the figure, the pin closest to the side pane is
the grounded one - and the braid should end up closest to the side panel
too.

You can easily verify which pin is ground with your ohmmeter - the other
side will have a high resistance to ground because of the blocking capacitor
on the RF board.
