Plugs around the ECU

[James]

I found a green wire with white stripe, white connector housing a fat single male spade tucked up in the wiring next to the ECU. And clue what this is or if it should be plugged in somewhere? I don't see anywhere for it to plug into.

It is a narrow band O2 output. For testing purposes only. Or you can connect it to a cheap O2 "blinky" gauge and impress your friends.

So in other words tuck it back up and ignore it lol.

I'm looking for odd reasons as to why my logger wont log.
