ECU wire(s) for getting Air/Fuel ratio signal

[ron_EA2A]

Does anyone knows which wire(s) for getting Air/Fuel ratio signal in the GLS ECU unit?

Depends on the Year your GLS was made... As I discovered when I fitted my CAMP, Mitsubishi changed the ECU design from about 1999 and went from a 4-block connector ECU to a 3-block.

I think i've got the pinouts for both somewhere here.

...Has someone been buying a Air/Fuel modifier then?
