i searched for answers but could find none.. my question is this: does anyone know what each of the four wires is (by color) on the primary 02 sensor...i want to hookup my wideband box and use resistors between the o2 heater power wire and the o2 heater ground wires but i dont know which one is which by color...also does anyone know what pins on the ecu these go into? thx -david

 

thats how i hooked mine up, your answer is in the evo forums, if it wasnt 4:30am i would find it for ya, and no, i dont remember the wires off hand. all i remember is there is 2 black, 1 white, and a blue. your answer is definatly here, cause i hooked mine up by finding the info on here. just be persistant with searching the threads in the evo forums, thats where it is.

i remember i THINK the thread topic was about how to wire a o2 sensor fix, it had the factory o2 sensor diagram there, i just dont know where it is, so search ur a$$ off, and it will pay off
