What cable do you need to connect to a later type diagnostic port on an M20B25?

The engine isn't in an E30 so I can't do the stomp test.

Can't find anything on Google to tell me how I actually connect to the diagnostic port itself?

Cheers,

On m20 engines there is limited diaganostic data but it plugs into the big round plug in the engine bay, the one you use to reset the service light
