Hey Guys,

I have a 89 240sx that I just pulled SOHC motor out and swapped in a 95 DOHC which I believe is OBD1 cause it has a single wire o2 sensor, correct me if I am wrong.

The problem I am having is I have the upper harness for the 95 motor for the engine and ECM and I am trying to find out how to connect it to the 89 engine room harness that connects to the fuse box, I have already been able to find out what the color wires for what pins are on the 89 side of the harness ( connectors E9 and E10 ) which has to do with AC relay, ECU backup power, ignition switch, EGT sensor, ECU power and sensor ground, park switch, etc...

Now when I try to find info for the E17 and E11 connector on the 95 ECM harness it doesnt match my wire colors. For example, my e17 connector (gray 8 pin connector) is:

[Pink, Blue, Brown, Gray ]
[N/A , Gray,B/W , White]

but when I read diagrams I've found for my motor it says they should be like:

BR, R/L, Y/L, Y/B, B, BR, Etc.

I know most people would say just swap to an s13 dizzy and intake manifold plus the s13 ECU wiring but I don't wanna have to do all that if I can just find a way to wire this up right since everything is ready to go in the car except the wiring right now.

Please if anyone could help me I would appreciate it so much

Can anyone Atleast maybe direct me to some more 95 wiring pinout diagrams? I'm pretty desperate at this point, the cars been sitting on jack stands at my buddy's house for 2 weeks now cause I can't figure out the wiring.
