In your dme box, after the engine harness has been removed, you will be left with a long grey rectangular dme connector and 3 other connectors with 8 pins (one on a manual transmission car), This should fit this early style harness

These are configured for automatic transmission cars, but can be used in a manual transmission car by omitting connectors and running one wire to the CAS if the car is converted to automatic, if it is staying manual no extra wire needs to be run.
