I am rewiring a secondary o2 sensor for a 97 civic dx w/ ex swap. I am using a ex engine harness. I rewired the 4 wires from the ecu pin to the sec.o2 sensor, but check engine light still comes on. I already know the ecu pin 4 the sec. o2 sensor. Can anybody tell me the 4 wires from the sec. o2 sensor? Example: 1 green,2 blk and 1 white.
