Still no time to go into the workshop, but tomorrow looks promising. However, I almost finished the drawings. There are still some details to work out and the real world work will surely involve some changes.
The drawings are in the article.

I put all the drawings in one[fr] filer.

Still no time in the workshop but work on the wiring diagrams goes on. I'm almost done, the most complex one remaining being for the flaps.
The others can be downloaded in the following article. Some are modified on a daily basis after the systems get more and more integrated, I get answers from the harness makers and correct my errors.

No time to go in the workshop due to a cold and a quite full work schedule. So I work on the wiring diagrams by adding the intercom, VHF-NAV and transponder files. They can be uploaded in the following article.
After having drawn the circuit I pulled the VHF and transponder harnesses out of the box, and surprise they were not wired as I would have done it especially with the wiring of the shields. Without doubt the harness maker is correct so I will ask him what to do about this little snag.

As there are quite a lot of wires that have to go through the firewall, I install to passthroughs fabricated by a neighbour, thanks Didier. The assembly is done by soldering a big stainless steel washer to some stainless steel tubing. A second washer will be used to sandwich the firewall between the twi washers.



This is the cabin side once installed.



This is the cabin side. Once all the wirings are installed, the whole assembly will be covered with heatsleeve and fireresistant RTV.

Some wiring on the firewall forward. I first identify all the EGT and CHT wires. A total of 16 wires to identify and 16 pins to crimp. As the wires will have to be cut on the cabin side they are only identified at the end. The picture qhow two markings and the pins. The engine side wire marking is visible on the left (white E).



Then I put some heatshrink around the pins.



I also began to prepare the harness for the electronic ignition.
