So I swapped a b18c5 into my Honda Challenge car and I am pulling code 41 - O2 sensor I am converted to obd1 using a hondata my questions is. Do I need to wire the new o2 sensor into the wires that used to come from the front o2 sensor or the rear one?

I have a brand new 4 wire O2 sensor I ordered is that the correct one (#27 in bottom picture)?

The car is a 97 hatch with a ex harness.

Thanks guys.

Basically do I need this 02 sensor


or this one # 27 (this is the one I ordered but is does not plug into my harness)

front, obd 1 doesn't look for a secondary O2 sensor
