94 pcm pinout the same as a 91

[damnford]

i found the pinout for a 94 and was wondering if it is the same as a 91 so i can check the wiring on my 91.

Thanks for that chart!! I saved to my files

The 91 and 94 PCM pinout will be SIMILAR but not exactly the same

In particular the barmetric pressure sensor. That was not there on 92-94 models. Also 93-94 had two inputs for O2 sensors, 91-92 only had one.

Also EGR, correct?

Also EGR, correct?

California 93's and all 94's, yes.

i finally got my wiring diagram it is in a tube and has to be rolled out and unfolded.

I could certainly use the pin diagram for a 92' if anyone has a link or access. Google bouncing me all over.....
