o2 sensor

Hi, this has prob been asked a million times but which wire do you cut on the ecu? I know it's no:23 on the big connector but with out a manual how do you tell which one that is? cheers

Hi go to the maintenance section,there should be a PDF manual there.

Briliant thanks, the only bit that throws me is on the download the 2005 model ecu is showing 2 no21 ports? so hope is correct as would totally place no23 in the wrong location.cheers

Yes thats right & the port numbers are actually embosed on the ECU when you actually look at it. Lots of members have done this with never an issue reported

As crash says, its on the ECM as well.

Thanks for the help.
