I wouldnt waste your time personally as its as good as usIess

 

Where is the sender.

It was a freeby so will fit it in the mean time, as it fill a hole in the second pod.

 

 

Purple (sender) should be a taken from the signal wire on your stock oxygen sensor. (just after the turbo on the downpipe).
However I do agree with frayz, a narrow band air/fuel ratio gauge is more of a "cosmetic"value...

 

Thanks for that, with regard to the cosmetic value, theres not many scoobs running about with all non-cosmetic mods.

 

is advisable to connect that wire directly to ECU pin.

 

What one?

 

the purple one. the pin depends of your model year and version.
