Thank you guys for your feedback, just to make story complete i know where is DME its from begining diassembly on my desk. I am electic engineer and a friend reach me he need help to fix dead car. Somebody kill DME and car was completly dead. I was able to fix DME and now the car seems to work, i mean dash board is alive atc. But there is no spark. Thats why i need the wiring. I do not suspect DME relay as the dash works and i smell petrol. I am quite sure somebody kill DME igbition final stage component and i cant find new so for
Ithanks to bcameron59 I got wiring but its again the same which I had allready. but the 96 i am working on is different I can see it even on ecu pins, my DME have 88pins instead of 55 mentioned in the wiring schematic. sorry I am *** its my first Porsche I am working on and appriciate your model knowledge
I found a photo of the pins on a for sale ad for 1996 993 ECU and you are correct, there are 88 pins in total.
However i wonder if all of these are active, ie connected to a corresponding wire on the female plug. You might be able to (carefully!) remove the tape or sheathing on the wire bundle and count the number of wires that are actually in the bundle.
it would not be the first time i have seen porsche use connectors where all the positions are not in use.

They are not all active but most of them yes. Anyway they do not match 55 pins DME and thats way also wiring is different. I need wiring for this 88 pins DME.
Ah, now i see your dilemma - the wiring diagram identifies 55 positions (a few unused) but those don’t correspond to the 88 positions on the connector. Found some info posted by our guru Bill Verburg on another forum which I hope will help you:
I have this guru pin description already. The problem is that the rest of the wiring dont comply either. For example i did not find any ignition module under the sewt but find two ignition modules in engine area. Long story short i need wiring schematic for 96 model as it is com0letly different and so 95 is not usable
Big thx to Bcameron he send me correct 88pins DME wiring which match the 1996 US model. So now i can confirm wiring is OK and i need to get new DME ignition drivers. It seems it is imposible. I contacted Bosch but the do not know the component. I fix the car up to 90% and now i dont want to give it up. Any chance to source compoment BOSCH 30045???? See picture
Hi,
it is possible to get a copy of the 993 wiring diagrams.
Thanks in advance.
