Tony’s Praline & Honey ham injection, anyone use it on Boston butt?

My neighbor gave me the butt because he needed the room in one of his six freezers, so I decided to experiment.

I ground up some dried onion (basically made onion powder), mixed it with this injection, plus did my normal black pepper, salt, garlic (and marinade) rubbed on the outside.
Anyone here ever use this marinade on a butt?

Too sweet?

It’s back in a vacuum bag, I will smoke it Wednesday.
