O2 sensor eliminator not working on CB1100rs 2017

[Houtman_imp]

Here is a place in the UK that sells them for the ‘17 : https://picclick.co.uk/Honda-CB1100EX-RS...53683.html

However, Houtman said the ones he got from somewhere in the UK did not work on his RS. YMMV

Would anyone know whether the EX / RS would indeed need two O2 sensor eliminator plugs, or is one of these plugs (connectors) enough ?
Thanks

I had two of them on my 2017 EX , did not work , two on my 2014 DLX worked perfectly .
