Wiring for Techedge wideband

Could someone with a brain have a look at this techedge page and let me know if I am reading it correctly. http://www.wbo2.com/sw/wblinout.htm

I am planning to wire my S60 as option C at the bottom of the linked page, so + to pin19 and - to sensor ground with no shunt installed. Is this the correct option?

Planning to run power via the spare output pin on the fuel pump relay so it is only heating when running, is this sensible? It only draws 3A so should be fine.

Thanks
