Thanks again Lee,

Its cold and late here but just gone out to the shed again to recheck the Noid light side to side.

The illumination is noticeably brighter now the sun has gone down in the drivers side so I think your earth prognosis has merit, especially as I have had a number of earth issues already with this harness.

Will use the power of the internet to find where the PCM earths the injectors.

Thanks again.

Paul
