I still need to find out which wire on the 02 sensor is the signal so i can hook up the air fuel ratio guage, there is 4 wires ( 2 white, 1 gray, 1 black) is someone could tell me what wire i connect the 02 sensor to that would be great. i have a autometer air fuel guage ( the purple wire is the signal wire) please helppp! its sooo frustrating !

 

i think you need a new sensor if i read this correctly, im not sure though i just did a quick search for you, i dont know much about that.....http://forum.2gn.org/viewtopic.php?t...air+fuel+gauge....hope this helps, i was tryin to get some help yesterday and no one responded lol....keep us posted
