Hi Guys

I have looked every where, any one have one its S15 Manual ECU code number 23710 85F04 NN Pin out.

I am about to rip my hair out, nothing I can find matches. This one is the closest I can find but there are some rouge missing wires http://ebookbrowsee.net/sr20de-ecu-pino ... d271119634
I cant match them as it doesn't have the color chart.

This is for an S14 SR20DE, but may help.



Good luck finding exactly what you're looking for though, it took me literally years to find this pinout list.

The bright side is that your ECU isn't an oddball Autech unit, or one of the myriad of options that plagued the '00 and up models. My list has it simply as an NN labeled manual transmission SR20DE ECU. But the only manual I have on my hard drive, and uploaded to our FSM library is for the turbo model. http://www.nicoclub.com/FSM/240sx/S15/S15/ In the S13 models, the differences between the DE and DET is usually pretty minor (my current setup uses a KA harness with a few extra wires ran for the coils for example), but with newer model stuff, there's inevitably more crap that gets changed between trim levels. The fortunate side is that the S15 was still based on last gen wiring design, so it's fairly modifiable (simplistic) compared to modern stuff with integrated CAN channels.

Running into a similar issue here myself. I have an S15 SR20DE with a QQ ECU - Supposedly, it's supposed to be an NN ECU.

Do I need to scrounge up an NN ECU or can I just order the NN harness and carry on?
