2005 EX - Need help with hard-wiring Secondary O2 Sensor to ECU

FLUXXX

New Member
Greetings Forum, I have swapped engines, ecu, and transmission from my 2004 Civic LX into my 2005 Civic EX. In the process, I have to deal with the Secondary o2 sensor which the 2004 LX did not have. To make things more problematic, I am utilizing the 2005 ex engine wiring harness but the 2004 cabin wiring harness. So, what I really need to know is in hard-wiring the secondary o2 sensor to the ecu, where would I insert the pins from the o2 sensor into the ecu plug? Thank you in advance.
