90sc vs 95sc wiring diagrams

not too long ago a nice fella from one of the northern states sent me a newer ecu and im just getting around to doing another 95 ecu swap in another one of my 90s, didn't find this anywhere so i figured i'd post this here so if anyone searches in the future they can find it

search words: pin out, ecu, ecm, pcm, wiring harness, ecu swap

95sc diagrams first

just one last 95sc6 image


and 4 90sc images

-enjoy

Hey great post, thanks!

Wait, you can do that?

And why?
Just wondering.

I'm not sure either, curious myself.


If I had to guess, this is so he can run a 4R70W in place of the AOD

no i swapped a 95 ecu in my 91 when i swapped in the 4r70w, this one im referring to here is one of my black 90 5spds, im swaping the ecu because i dislike the lack of control the older ecu's have, im a bit of a perfectionist and the newer ecu is more appealing as i have more knobs i can play with, plus it was given to me and is otherwise just laying around so i figured why not?

its simple enough, a few pins just need to be moved around but the czaw0 strategy doesn't have the goodies to support tfi, so a cbaza tune needs to be modified for it, unless you want to swap to the 94+ edis setup then the czaw0 strategy will suffice minus the changes needed for injector/maf/egr differences if any
