I think it's a pretty cool project and you're doing a great job! Keep posting!

Merry Christmas to you all.
Thank you Aop, Dan k, and Darren for your interest.
I will continue with this over drawn (more ways than one) project.

The console needed rewiring, particularly having the necessary wires from the various switches and panel lamps to the three terminal strips. I never done a wire harness bigger than what you might find in an old transistor amplifier. This required a completely different approach than one done in situ. I discovered several sites which showed how they make harnesses for automobiles and such. They use a board with anchoring points to create an measured out harness map. So I decided to do the same. It took longer than I thought to complete this.

Then I I attached the top half to the underside of the control panel. There is close to fifty wires going to various parts. It is not as neet as I would have liked it, but nobody is going to see the underside unless they look up into it (through the perspex front panel).

Then I placed the whole control panel onto the console and then attached the bottom half of the wiring harness to the three terminal strips.
In a way I was pleasantly surprised how well the harness terminals were easily aligned and installed.

Image

Now the opposite terminal, of the three strips, needed to be wired also. Most of which were routed to the two 25 pin D-connectors at the rear of the console.
These feed power and data to the control box under the display table (via cabling, I think. Not yet decided).

Added a Passive Infrared (PIR) sensor to the interior of the console.
This will activate the display whenever someone walks near it, and nobody else is operating the display.
The PIR had to be above the kick-board, so I made a slanted bracket to follow the lean of the front panel area.

Image

Then I added some grey dyed felt around the edges of the console. This is to seal the perspex sheet from dust etc.

And by the way.

Drilled holes in the thick Perspex, allowing heatwaves to reach the PIR sensor. A portion of the front panel was used as a kick board to protect the Perspex.

The PIR sensors movement in its vicinity. When it does it will turn the console lighting on. The only times it turns off is when the PIR no longer sensors movement for 10 seconds, or when someone starts working the console.

Thank you JB for encouraging response.
_________________________________
Now that the wiring diorama is basically completed, I can forget about that part of the project.
At this stage I started thinking about the landscape. That is, the river bank areas.
Here is the North side. My first objective was the staircase, and build from there.

Created footpath under the bridge and up the hill.
