The technical data book that I have for the 1989 - 1994 964 shows a detailed control unit pin layout for the tiptronic transmission vehicle but not one for a manual car, can anyone tell what are the differences in the pin layout if any, or where would I find the same layout for a manual 964?
Thanks as always.

You can get some decent results just hitting the google image search with "964 control unit pin layout DME"

Hope that helps.

Thanks for the feedback, however, I searched here and the web previously before posting. I have the diagram of the DME, what I am tring to find is a pin layout that tells whether the pin is an input or output pin, similar to what is in the Technical data handbook for the Tiptronic.

The manual and tiptronic gearboxes use the same DME control unit. What are you attempting to do?

Hey Biggles I may have what you need ..What I have is the 19 pin connector with the labels telling what pin is what I will try and attach if not I can mail it to you .Randy

Now I may have used terms out of place, so apologize for any confusion and will attempt to clarify, as lways, appreciate the feedback. I am looking to add AEM to my car, so need to have a true pin assignment, basically which pins are input and output pins as well as true designation. This is a copy of the pin layout from Bentley for the Tiptronic. I am trying to see whether there is one for the manual or whether this applicable?
Thanks as always.

You can find the pin assignment for the DME control unit HERE.

Hey sorry about that but anyhow I have found the pict I sent you to help in case you do not want to get the adaptor for testing the DME you can just use 4 wires from what I can tell. I have had my battery disconnected for about 6 weeks repairing a alt fan bearing so I may have to reset the dme. Should have it together tomm just have a lot of irons in the fire.
As for the pict I sent ya from Maxwell Smart "Missed it by that much"

The 964 DME ECU does not have any nonvolatile memory unlike the 993 ECU so just disconnecting the battery will completely reset the two "learned" values, i.e. idle speed opening and short term fuel trim.

No problem, we are in this together.
Thanks!

I have a mysterious occasional power problem (rarely, the car runs really well and is super fast) and I suspect something in th wiring harness. Any tips on how to start testing these pin outs?
