944S2 DME Pin-out Diagram

Anyone have a 944S2 DME pin-out diagram?
Swapped an S2 motor into the race car and am unable to get spark.
Made necessary 14pin connector changes
Installed Ignitor and wiring
Verified good crank sensor, DME, Ignitor, Coil etc.
No factory wiring other than the engine harness.
Power to coil
Fuel
Injectors firing
NO SPARK

Thanks!

Here you go....

I had to derive this myslef using in part a 964 DME assignment - they are very similar.

Thanks, as suspected no power.
The 2.5NA has a 4 pole connector off the wiring harness by the DME which for the most part controls the tach. The S2 has a 14 pin connector which requires power to pin #5 to feed the DME. Looking good for solving the issues......except there is no pin in the #5 spot on the 14 pin connector......
Digging deeper. Need to figure out the wire coming off the #18 pin on the DME and follow it back through the harness.

Now why couldn't I find that when I went looking for it. That page (7 and 8) isn't part of my Vol 1A. Have you got page 24/28 - 7 as well??

Thanks

Eric

Where would I find the wire designation color chart for the DME cable?

You will need to look at the DME / Engine wire harness schematic. I can scan those also if you need when I get home.

Edit - Forgot to add, let me know what schematic you need the scan for.. your '85.5 944 or the S2 harness.
