Howdy folks, need a bit of help with some wiring up for a D15B from an EK3.

Basically i'm putting an injected D15B from an EK3 into my EF2, from which an injected D16A9 has just been taken out. What I need to know is, is the D16A9 engine loom and ECU OBD0 and is the D15B loom and ECU OBD2a? If so, it'd be great if people could confirm that for me and if not, if people could let me know what they are.

Secondly, as i'm putting in what I think is OBD2a into what I think was OBD0, can people tell me what I need to make everything plug together smoothly and what jumper harness I may need, where for and where to get them.

Thanks a million in advance for any responses!
