Here is something I learned from a magazine that you may want to try. It works GREAT for me. I can use one had to hold the wing, and the other to plug in all the wing connections.

I used two pieces of 1/2 x 3/8 balsa, set the female (arguably male) connector on one piece, drew around the connector, removed the wood so it would sit completely down inside, and then screwed them together so they could be removed if necessary. The cut to width of the fuse, and ran screws into the ends from the outside. I labeled the connections from the wing with masking tape, and it works great--if I don't get the connections in backwards. In hopes of preventing this, I mounted them all in the same direction--all the black wires on the right.
