O2 sensor hook ups on B16a SiR II
 

Okay, i just finish installing my JDM b16a SiR II motor in my 92 Honda Civic hatchback CX. And i'm using the CX engine harness for the swap. Heard i suppose to use 92-95 Si engine harness though. But anyways, Since the JDM b16a SiR II has four wires for the O2 sensor. Where does each of them go. Well, i know 2 of them leads to the ECU. But where does the other two wire leads to?

i had the same problem with a 92 cx that had a y8 swap in it... 2 wires go to the ecu one for the o2 signal the other to the heater control sender. then the other two wires are for the heater control and have to have a ecu power and ground.

im pretty sure that what it was... if it is imperitive to get your car from throwing a code i can go out and chick the wires again and let ya know...

let me know
