I need a proper pinout for an S14 SR20DE "WA" ECU

[Seishuku]

Hopefully someone here can help me. The S14 SR20DET's ECU isn't the same, it has more pins than my 20DE's.The S13's is closer, but not quite right.

I've attached some pictures

Sad news friend, thats an S14 SR20DE MT ECU. It will not run an SR20DET.

Well that's good news, becuase I have an S14 SR20DE

I see, what pins do you need in particular, perhaps I can help.

Well, the pinout for the S13's DET ECU is pretty close, the CAS, MAF, knock, O2, and injectors are the same pins... However the tach and coil drive is a little different.The tach pin on the ECU is used to drive the coil in the distributor.

Now it also has two of the coil pack outputs going to the harness connector, and I'm assuming they are using one of those to drive the tach instead.

Also I want the pinout to make sure of the other signals (start signal, neutral switch, fuel pump relay, etc), the pins on the ECU seem right, but the wire colors don't match up.

Thanks for any help you can give me.

Well the S13, S14 NA and S14 turbo late model share the exact same connector style a few of the important sensors are the same. This is the best I am able to come up with. My roomate has info on some S14 SR wiring but I dont know where he keeps his binder.

I would assume the pinout or wiring colors for the late model S14 SR20DET are similar to the NA SR since most of those wires you are interested in are chassis related and not engine related.

Ok, cool. That pin 2 I have labeled as "Coil Pack 4", which is what I assumed. Which is a orange/blue wire, and that's the same color as the start signal wire, that's why I want to make sure.

Thanks for the help!

If you have an SR20DE you shouldnt have to worry about coilpack wires.
