Proposed double vanity

[New tradesman]

Sorry, I researched the other threads on this and couldn't see what I was looking for. I am adding a double vanity. I am attaching whats in the wall right now. I wasnt sure whether I should T into the drain line to the left of the current vanity drain or run a line horizontal and tie into the existing single vanity drain by replacing the fitting. Each drain needs its own vent right so running a new drain line vertically onto the 2 inch line won't work.

Here are a few around here.

Thank you. I am opening the wall tonight to see what is there. From what I can see the stack going up the vents has a T in it and the T is the drain for the existing sink and the top of the T is the vent.

If you have 1.5" pipe, then something like this.

Its 2 inch. I measured it since the wall wasn't closed up correctly when I pulled the existing vanity out.

I was able to go into the fitting on the right side. Wall is all sealed up. Best part is I just ran new PEX lines too. Works like a charm.
