This is connected to the MAF part of the wiring loom, is it for an Oxygen/lambda sensor?
I have no idea where it is supposed to go, I have no lambda sensor either so im thinking/hoping it's to connect to that?
Car failed MOT on Lambda test so need to get one wired up, the downpipe has a bolt in place of where the sensor goes but I cant find any wiring for it!
There is no sensor in the headers either, it's a version 2 car so it could have been there apparently!

It is for the lambda sensor.

get one from subaru, stick it in the exhaust and plug it in

Job done

Brilliant, thanks mate!

I was told the Lambda sensor wire is white with a silver band as their are only 2 wires that colour coming out of the ecu and one goes to the MAF i was hoping this one would be for the lambda sensor!

Sorry to bang on a bit but somebody else is telling me the plug is down by the bumper and should plug into the headers and this is not the plug, i hope your right then life will be simple!
How sure are you?
