Ok since i really don't want to go through of the hassle of selling my S13 KA AEM to just buy another AEM for my S14 (ECU connectors are different).

I decided i would give this a shot and just re-pin the ecu's and get away with that. (Would have to go and pick up a S13 ECU connector)

So i would just want to make sure that....


I cross-referenced all the pin-outs and got them all correct.
I'd also like to ask about a few pins since they were a bit confusing. Here we go
Also like to make sure if my ECCS grounds are fine as well

Here is the ecu pinouts for 91-94 240sx (KA24DE) for the AEM

You know that there are conversion harnesses for this that might work right? People use them to run ROM-tuned s13 ecu's in s14's.

Yea i figured that there would probably be conversion harnesses since i know some friends who have ran s13 ecus in their s14s, but they aren't readily available or sold. most of the time you have to make them,

which im actually in the processing of making one.

Enthalpy sells them from a third party I believe, and Emance (Jason) makes them. Seems like a fairly easy but time consuming project, have fun. I also feel like I've seen a write up or maybe just a blog about someone making their own.

Yea im not bad with electrical/wiring so i don't mind making my own.

You are right about seeing a writeup tho
