The motor/intercooler/exhaust are in the car but I have hardtime figuring out the wiring harness. The place where I bought them told me it was uncut but there are several cut wires & sign of soldering. So I really need a help from anyone who has knowledge about this type of swap. The swap is　S14 SR20DET Blacktop (220hp) Engine into USDM 1995 240sx SE.

Questions:

1. If I were to use the SR harness for the swap, would the wire just plugs in like the people say about s13 engine into 180sx? (excluding extensioning the O2 sensor,etc)

2. If not what do I need to do exactly.

3. I am pretty sure I can not re-use KA harness for blacktop (220hp) engine, if I am incorrect please let me know.

4. When I tried to fit 240sx's AC compressor, it didnt fit at all. Do any of you guys run AC with blacktop engine?

5. What does your S14 blacktop engine's ECU say because mine say "NA" so is it the right one??

please post more stuff if i left out anything. here are couple of picture of my harness.













Thank you for your time
