ttt ... help me out fellas

 

why cant you trace them back from the stock o2 sensor. i can say that there is two wires i believe the same color for the heater. then a gound and the o2.

 

well those wires are tapped up like a mo fo... but i did get under the car last night and looked at the colors of the wires...

orange with blue stripe
yellow with black stripe
green with white stripe
and a white wire....

 

i have a book that says yel/black (+) and orn/wht (-) should have 12 volts between them so i guess thats heater. and white and green/white are o2. white goes back to the ecu pin d14. and green/white is common with a bunch of other sensors. orange/ white goes back to the ecu at pin a5. hope this helps

 

holy **** man.. sweet.. you saved me alot of time!
