Default d15z3 MA9 civic 5 wire o2 sensor wiring help

Cheers everybody!

Theres an o2 sensor signal alternator or something in my motor bay.
My cel is on because of the primary o2 sensor so i would like to eleminate that useless little thing. If i cut the wires where i put the red circles and reattach them again without the gadget, it shall work fine, right?
Also, is there a special way to reattach them or i can do it simply by use some terminal blocks?

Thank you guys!

That thing is modifies the output voltage of the primary o2 sensor to bring richer mixture to the engine.

The code is P0132 witch is stands for o2 sensor high voltage reads.

Thats what i was able to find out, and why i hope that if i remove the modifier than everything will be ok
