Hi Everyone.
Did anyone know that the wiring in the MA8/MA9 and MB8/MB9 is slighlty different?
So now I accidently found a service manual for MA model. It was in 95 year folder and I didn't pay attention to it. Until today.
First I compared the wiring and remembered that the EG/EJ wiring is similar. I have earlier compared an P28 ecu (92-95 EG/EJ) pin-out to my MB8 pin-out. I have a D16Z9 engine waiting and I tried the P28 ecu. which also didn't work. Different plug etc. From ~50 wires I found matching only 5!
Later I noticed that the numbering system for the plugs is totally different.
In some manuals the count through the rows and in other manuals they count through columns. So I transfered the positions to a new system. And the picture is much better now.
Until now I was troubleshooting with the manual for the MB. That's why everything checks out.
Now I'm making final notes to what wires I have to change to make it work for the MA ECU.
