Hey guys. Just a question if anyone could help. Im trying to install a Air/fule ratio gauge but im having a lil trouble. Ive got 4 wires coming out of the oxygen sensor and i dont know which one is the signal. There is one grey, one black and 2 white. When i connectit to the grey, thegaugeis on optimal at idle and only goes up a lil bit underHigher revs. when i connect it to the black it ilde at optimal but jumps to rich as soon as i put my foot on the throttle. on one white it just stays at rich and the other white wire it jumps back and forth from idle to rich without me
doing anything. A guy gave me this photo but i couldnt figure it out becoz my ECU doesnt look anything like it or maybe i dont know how to read it?? Any help would be appreciated. Thanx
