Skimmed/re-read the Glastar assembly manuals I and II looking for the wing wiring connections for transfer pump and pitot heat. Did find them, and used butt connectors per the manual to tie in the left and right transfer pumps. Now concerned over the fuel capacity sender connections for the outboard aux tanks......there is NO inspection hole in the wing for the section with access to the aux tank. And you can't hook up the electrical to it until after it's installed. But you can't install the aux tank until completing top wings riveted on. And then no access. Catch 22.
