GM e67 ecu wiring required to read, write and datalog at obd2 plug with mpvi2

Hi Guys
Have a customer just fitted a lsa to his boat, came completely marine set up, the diagnostics plug they have a Deplhi 6 pin plug with four pins, 12v,earth,can high and can low.
Is there other terminals to be wired in to enable the use of a MPVI2 to communicate and function.(will make a patch harness)
Does somebody have a pinout for the MPVI2 and the required pins to use ?
Thank you................

You just need the two grounds, the power wire and the two CAN wires.

Attachment 116481

Hi Kevin87turbot
I'm missing the chassis ground on the set up I have, will add that and give it a shot.
Thanks for the help....

It should work fine. It's the same way my E67 benchtop harness is wired.
