Hi friends, I am new NICO club and I am glad to join all of you nissan lovers. I am currently looking for an engine/ecu wiring diagram for a Nissan crew na20p wiring diagram 1998 and sincerely hope that someone here might be in a position to help or at least direct me somewhere I can get it. Looking forward to your responses.

There are many ECU/ECM/PCM rebuilders and repair businesses available for this inquiry. Not even Nissan dealership service centers have this information because it is of such proprietary information. Nissan doesn't actually build them. You may be able to get one of the available rebuilder or repair businesses, you can find on the internet, willing to provide you what you need.
