Pin outs

[Didi]

Hi guys,
I am busy wireing up a 1UZ-FE for my Nissan 4x4.
I am using the standaard ECU part nr 89661-50241 with 34P-22P-16P-28P
connectors and un-cut engine harnass.
I can't seem to find the correct wireing diagram for this ECU.Some are close with the color coding but could not find a 100% match.

Can any one please assist.

Regards

I'm pretty sure thats a UCF20 LS400/Celsior ecu.

I don't think I have seen a pinout for one of those, but I haven't really looked.

The UCF10/UCF11 uses the same plugs, but I'm not sure in the pinout is the same. Highly likely that the colours would differ though.

pinout between ucf10/11 and ucf20/21 are different.

The nearst that I could find is a wireing diagram for the 89661-50160 ECU.
Same 34P-22P-16P-28P connections.
Pin nr's 10,11,15,17,18,22,23 are not the same colours.

I would prefer to use the Lexus ECU,I got the Spitronics ECU as a back-up if I cannot sort it out.


Thanks

Sideshow,thats what I am busy with now,since I cannot find a wireing diagram.I have done many conversions over the years but this is my 1st one with fuel injection.The mechanical side is the easy part for me.
