With the help of Eric, an awesome AV technician and A&P, I started routing the FWF wires - we put as much as we could of the other FWF tubing in place for reference, then routed the wires around it:
FWF area with all tubes in place to figure out wire routing
Spark plug wire routing from the coil packs
Sensor wire routing along the side of the engine
Sensor, EFII and spark plug wire routing near the firewall
This gave them the general shape/route, and we still need to finish attaching them later.
For the overhead console, I updated my insert design to avoid interference between connectors and screws by moving the O₂ distributors slightly outboard, and laser-cut mock versions out of acrylic to start (before making the real ones from CFRP):
Laser-cutting the mock inserts
Mock inserts, laser-cut from acrylic
Mock inserts made from acrylic, with all equipment attached
To make them fit, we had to trim parts of the overhead console flange, which was a bit painful (literally, we're getting old 🤣) but doable:
Trimming the overhead console insert flange to fit the O₂ distributors
They fit quite well except for the aft lights which were about 1/8" too far aft - since it was a small difference, and their face is offset from the hole anyway, I'll just move those holes about 5/32" forward on the final version of the panel:
Mock inserts attached in place with all equipment except rear lights
With the borescope, we checked that the nutplate rivets, although close, did not hit the O₂ distributor connector:
O₂ distributor connector distance to the insert attachment nutplate
O₂ distributor connector distance to the insert attachment nutplate
Next I'll have the final versions of the inserts waterjet-cut in carbon fiber, route the O₂ tubes, and install it all for good.
