From the research, I would need a 7.8 DME with a modified 2002 engine harness? The two harness are very different from each other. I need from someone that has done this swap before?

The top is the 2003 has extra connector that seem to plug into another box and bottom is 2002, they all plug to one box.

I thought the 2002 was a 7.8 DME

Did the 2002 have the dual VarioCam like the 2003?

If it did, try using the 2002 harness on the 2003 engine.

Or you could source a 2003 manual harness.

You could try the 2003 auto harness and leave the tip connector unhooked.
