Your OMVL system should have the same diagnostic plug as a whole range of badge engineered injection systems. My diagnostic cable works with a whole host of different systems. Just buy the cable kit you showed from ebay and it should work, depending on your computer's age the cable will need the USB drivers off the supplied CD or the computer can download one itself off the net.

you'll see that there are two plugs suitable for early and later diagnostic connections.
