Put the raisins in the small bowl and cover with hot water. Set aside until the raisins are soft and plump.
In the large mixing bowl, whisk the whole wheat flour, brown sugar, baking soda, ground cinnamon, ginger, and salt. Stir in the carrots, zucchini, coconut, walnuts, and wheat germ.
In the medium mixing bowl, whisk together the eggs, oil, orange juice, and vanilla extract. Make a well in the dry ingredients and stir the egg mixture into the flour mixture, making sure the dry ingredients are evenly coated. Drain the raisins and stir them in.
Scoop the muffin mixture into the prepared muffin tin, dividing it evenly. Bake in the preheated oven until the muffins are completely cooked through and a toothpick comes out clean, about 25 minutes. Remove from the oven and cool in the pan for 5 minutes, then remove the muffins and finish cooling on a wire rack.
