Is there any way I can get it clear?
I can't make out any of the writing on it even on a pc.

The lower one was the one I have, it would have been perfected but it does not give you the colors of the line. And you can't back track the wire to the harness because you can't take apart the ECM wiring harness to see what the color of the wire is.
