which are which? i know the green, black black, white o2's but not these
can i still use this o2? obd1

 

The two whites are the heater grounds, the grey is your signal wire and the black is the ground. So the two whites=two black wires, grey=white wire and black=green wire. The sensor sounds like a bosch replacement o2 sensor, they do work.

 

thank you !, now are you familiar with hondata?

i have a p28 ecu from hondata, the led in hondata will be solid, until i plug the serial cable into it, than it will blink slowly.. .

and i can't get the hondalogger to recognize that it's connected.. it just says serial # s00-00000

laptop is setup right, fifo turned off.. any thoughts?

 

2 o2 sensors, same connectors

the grey wire is in the same position as the green wire on the connector

????
