GM E67 ECU Bulkhead Connector / OBD Info Req'd

[356Speedster]

Evening. I'm looking for some help on the Bulkhead Connector & OBD-II connectors on the GM E67 ECU.

Firstly, the OBD - Does anyone have any information on the live data that's made available from the port?

Secondly, the B-head connector - Same question, does anyone have any detail on the pinouts, also, I need the second half of the connector, but can't find it anywhere. My ECU harness has the female side of the connector in place, so I need the full male side to wire into if anyone can help locate one in the UK.

Thanks!
