O/T Zojirushi Zucchin Bread help

Been without my Z. bread machine for about 4 years, just got it back a few days ago.

Here is the recommended Zucchini bread recipe:
SPICED
ZUCCHINI BREAD
3 Large Eggs,
beaten lightly
1/3 cup Vegetable oil
2 cups All Purpose Flour
2 tsp. Baking Powder
1 tsp. Baking Soda
3/4 cup Sugar
1/2 tsp. Salt
1/2 tsp. Allspice
1 tsp. Cinnamon
1 tsp. Orange Peel
When beep sounds add:
1 cup Shredded Zucchini
3/4 cup Chopped Walnuts

I will omitt the Allspice,orange peel and cut the sugar some.

Now, I know nothing of this but would like to add some rum, what/how to add something to keep it from being "Wet" or what do I cut???

It's a loaf pan so probably no exta room.

Suggestions welcome,
Thanks,
Bordello
