Pitot wiring

Tonight I finalized the pitot wiring. I have a separate connector at the wing root for pitot heat. Since I had previously planned for a regulated pitot tube, I had three wires run to the pitot tube. With the unregulated model, I don’t need to use the third wire, so I’m leaving it in place as another spare wire.

I unpinned the pitot heat wire from the standard Vans wiring harness and connected it to the separate Pitot heat molex connector, then ran another ground wire from the pitot heat molex connector to the ground point on the fuselage. At the pitot tube end, I installed pins on the wires from the pitot tube, but held off on installing them into the molex connector. I need to wait until I have installed the mast, and the pitot tube, routing the wires through the mast in the process. If I install the connector now, there won’t be enough room to fit the molex connector through the mast.

Anyway, it was a fairly quick job to get this all finalized.

The four connectors at the wing root are a little overkill. The two on the left are standard Vans wiring harness. The third from left is the pitot heat connector, and the right hand connector connects spare wiring that runs to the wingtip.
This is where the pitot mast will attach. The wiring will plug into the molex connector on the right. The Pitot and AOA lines will attach to the white and blue lines respectively.
Feeling pretty good about progress so far.
I went ahead and retrieved the bottom wing skin from storage. This has some history, having been partially attached to a different left wing earlier in the build. I was very careful when I removed it from the original wing, and it’s in great shape.
