As always, thanks for your feedback, Weld.

The Delphi, MT05 diagnostic plug only employs three wires, as shown in the Delphi service manual.



The OBD2 code specifies the following wiring, as shown at the link below.

Pins 4&5: Ground
Pins 7&8: K-Line
Pin 16: +12V Battery

I might as well convert the RX3, 6-pin Delphi connectors to 3-pin Delphi connectors, which I can get from eBay.

I am inclined to purchase the following adapter, and wire the correct OBD2 pins to the corresponding Delphi pins, using one of the 3-pin Delphi connectors.

I can then connect this OBD2 adapter harness to any OBD2 scanner, such as the inexpensive, OBD2 scanner shown in the link below.
