Which S14 SR20DET is it? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Pumpkn · 06-23-2012, 08:30 AM

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?

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.
