Shower Drain to Toilet Drain

[mdudlik]

Hello All,

Some very novice help needed for what is probably an advanced project.

I need to install a shower/tub drain that drains into the toilet drain that's already installed. I have images here: http://imgur.com/a/4UkaT

Any help with what I need to get and the best ways to do things would be incredibly helpful.

I think this is the arrangement I'd need, i just don't know the connection needed to get the new pipes to drain into the old ones.

where are you located? different states/cities, different codes

I'm in Brooklyn.

I'm going to get a 4"to2" Wye, a trap and then the pipe to connect them.

ok, good luck
