Adding a downstairs toilet to existing waste pipe

[wayneec]

I am thinking about adding a downstairs toilet to the existing waste pipe found in the corner of the house. Only problem is I am not sure what plastic pipefittings I need (To get me from the existing waste pipe to the new toilet)
Also any tips on breaking into the soil pipe will be helpful as it’s in an awkward place

Any advice most appreciated
