OK I gotta admit that I have done nothing at all on the panel so far. This is something they do for us.

Below, this lady stretches wires to run right along the black lines drawn on the board. If she runs the wires of justy the right type along just the exact length shown on the board, then she will have the entire wiring layout of an Evolution!

After she takes the harnesses off the board, she runs wires too and from clearly-labelled points on this little jig. When done the wires will go to and from all the right places, in all the right bundles, to make a perfect wiring harness.

And here we see behind an instrument panel!
