I was installing a post cat (rear) o2 sensor on a 2001 subaru legacy gt wagon (2.5L sohc) and I made a mistake. I pulled out the 4 wires of the old o2 sensor from the “pig tail” connector. It looked like they were supposed to be removed. Anyway, now I don’t know the order of the wires. What do I do now?
fyi I used a bosch o2 sensor (with smart link?) I got from a mainstream auto parts store.
I’m sure I’m not the only person who has done this, it’s funny because the directions state “DO NOT REMOVE PIG TAIL WIRES”–too bad I didn’t read the directions until after I made this mistake. ha ha.
