Add Washer Drain to Basement Ejector System

I have an ejector system in my basement that services the bath that is down there. I would like to add a drain for a washing machine. I made a poor drawing of what is currently in place, and what I would like to add. I circled the portion that I would add.

Anything wrong with this plan?

Where it says "plugged" is where I would be connecting the washer drain. I would tie into the vent for the sink.

Also, this bathroom has been unfinished since we moved in. I'd like to close up the walls with sheet rock, so if any drain/vent issues are apparent, don't hesitate to point them out so I can repair them first!

Very good!!! That is acceptable. Make sure the vent ties in above the flood plane of the lav. You should be good to go.

Where is the current drain? There is none. Tired of using the laundry mat, hence the upgrade.

"in above the flood plane of the lav."

Pardon my ignorance, but what is the flood plane of the lav?

Tie the vent in above the level of the top of the sink.

Uh oh, problems!

So I twisted off the 3" plug on the end it is not what I thought it was! In fact, it is just a tube down into the ground, sealed on the bottom. It is about 3' deep. I think it must have been a make-shift safe. There was a a couple of empty zip-lock bags in there, and a plastic bottle. Anyway, so I am now back to how to the drain problem.

Here is my 2nd though:

Basically, I put in a wye under the sink drain by the floor, and run the pipe over to the washing machine. I'll have to do a little construction work on the wall behind the sink to get to the pipe, but it wont be too bad. Is this new plan still OK?
