GM Marine 10-pin DLC?

[Andrew K. Mattei]

Question for those who have dabbled with GM Marine ECU's...

I was just going through the Vetronix catalog and noticed that the Marine
ECUs use a 10-pin connector. Is this 2 rows of 5 pins, top row Left to Right
(A B C D E) bottom row left to right (K J H G F), with a slot on the bottom
center for the key?

If so, anyone know of a source other than Vetronix for these?

Thanks for any hints or tips!
