It would really help if you told us what model Cardinal you have.
We have three the front is a double side is the shower...the other is the black which means the also gets the water that goes down the bathroom sink. At the rear we have one for the other words the kitchen sink. All three tanks on ours are 30 gallon tanks.
At the bottom of my post is a 'signature' lists the camper and truck we pull it with. You should add yours. Someone with the same model as yours can chime in and give good advice on yours.

I have three valves on my Cardinal from front to back Black, Grey , Galley. What I did to figure out which was which, Make sure all tanks are empty fill one then go see what valve handles that area, and so on. Once I did that I took a piece of black to mark that valve and greg to mark that.

If you can see the plumbing attached to the dump valves, one pipe is probably larger than the other two. That one is the black tank dump valve. The smaller ones will be grey water.
