Hello!

I have ford sierra with 2.0i CAT pinto engine (N4B I suppose?), problem is with lambda sensor it is dying or already dead. Also CAT is cutted out a long time ago, so there is no need for lambda sensor anymore, so my question is - is there possible to fit ECU from earlyer 2.0i pinto without CAT (N4A it was, I think). I know, that it isn't direct fit, but what i wan't to know is that is there needed any other wiring to N4A ecu? Or i just can change pins in ecu plugs and plug older ecu in? Also maybe someone have pinouts/wiring diagrams for 2.0i pinto CAT and for usual 2.0i pinto?

A new Lambda sensor may be cheaper than another ecu.
It is certainly a lot easier to fit and a lot less work and worries.

I have spare ecu from N4A, thats why it will not be cheapier to buy a new lambda.

Any help about pinout?
