Which S14 SR20DET is it?

[Pumpkn]

Picked up my first s-chassis, 93 hatch that has a S14 SR20DET in it- the wiring is AWFUL. So I want to put in a wiring specialties upper and lower harness and go from there.

What I dont know is which harness I need- a dropdown box asks me which SR I have-3 different zenki choices and a kouki choice. Well, the ECM I have has the code NA on the side which designates kouki- however its a Mines tuned ecm and this SR is stock and I am not sure its the correct ECM.

Thanks for the help

It's a na ecu it's impossible to put any other ecu into the na harness

Is it possible for the harness and ecu combo to be wrong for the engine?

post up the ECU P/N and I can tell you exactly what year it is

If its a mines ecu then its still matching the na mark on it
get the harness that goes with it
mines ecu is just a daughter board with a tune
if u want to kno the tune u can email mines with nissan serials

You could get the wiring specialties (NA) harness and order a PFC for it. The new pfc works for all s14, 96 - 99.
