Thread: U13 ECU pinout

Anybody?


I have pin#25 but non in B13 SE-R and others.

Please....

What is the wire color? I did a lot of searching before publishing my OBD1 pinout diagram, and couldn't find the U13/U14 diagrams. The OBD1 diagram I posted is accurate for all other OBD1 though.

I really appreciate the comment bud. The color is Orange/Blue.

I did try tracing it with the U13 harness i got. From Pin#25 of the ECU, it goes to socket "F14" which connects to Main Harness (dashboard harness).



Thanks.

Looking at the diagram, orange/blue is for the ECM relay. I'll go out to the garage right now and look at my harnesses.

ECM Relay is pin#38& 47 which is orange/blue in B13 SE-R while Orange in U13

Thank you....

Okay, so PIN #25 on a Nissan Altima (U13?), is for the power steering oil pressure switch.

Also the same on the '95 240SX. Power Steering Oil Pressure Switch.

NOTE:

S13 Silvia: O/B wire is for Exhaust Over Temp Warning Lamp

S14 Non European Sr20DET -

O/B - Wastegate Valve Control Solenoid Valve

oh my...

do these mean that the U13 i have is really different from B13? now im in deep sh!t
