Well, I thought I was smart with my approach.  But some of you guys have a
simpler installation.  Nevertheless, I installed the Piper (I believe) round
ground power receptacle just under the lever for the canopy.  My battery is
right behind the pilot's seat.  It's a nice installation that I frequently use
and any line boy can deal with it if necessary.  I got it from Aircraft Spruce
and I chose it over the Cessna plug because it came with an attached cover.
