It is 4, all of them are.should be 4
but you do know that you put the o2 sensor in your ecu and not spliced into one of the sensors, right?
oh geez, sorry about that. i was thinking o2 simulator. my bad, thanks for catching that. you are completely rightIt is 4, all of them are.
What? Say that again please.
Cutting the old sensor wires after the connector and soldering the new one in, thus retaining the connector should be how it's done.
I'm not sure if that's what you meant or not.
