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
