S14 ka in s13
 

I picked up a 90 240sx, I bought it from a friend who unknowingly bought a s14ka ecu and harness and engine , I have the s13 body plug ,the brown plug and gray plug. I'm thinking it will be cheaper to to make the s14 harness to work,any have any info on this?

i have been searching, but im looking to keep all the 95 stuff, not switch the intake. and im having trouble findind the correct body plug diagram for a 95 engine harness

The factory service manual has all of the wiring diagrams.

Is it too far a stretch to buy an S13 harness and ECU?
That's all I did when I put the engine in my car
