On my 7afe the upstream(front) o2 sensor has two wires one ground(brown) and one signal to the pcm(black).
I dont have that two bolt setup any more for that sensor and will need to put in a standard o2 so i was going to put in Bosch universal #11027. my question is since its a one wire connection the sensor it self should ground out...right? |

i put that one wire in and everything is working fine, the exhaust should be a good ground, the oringinal ground was linked to others and attached at the intake mani...not like it was going straight to pcm ground or anything
