Right wing wiring

I spent time securing the right wing wiring today. Zip ties along the length, and some RTV in some places to help secure everything and keep it from rattling around in places where the wiring bundle was loose within the snap-bushings.

Autopilot roll servo

Today I installed the autopilot roll servo. Having done this on the previous set of wings, this went quickly. I also installed the bell crank, the adel clamps, and torqued all the bolts.

Installed and wired up
Install finished except for wiring tidy up.

Right wing systems and spare wiring

Today I spent time running the wiring harnesses through the right wing, and installing the spare wiring molex connector bracket. This is my own (Vans approved) modification to make it easier to add more electrical devices in the future.

Riveting on the spare wiring bracket. Look at that grey hair

Wing systems

Tonight I enlarged one of the wing systems holes to 5/8ths to allow two pneumatic tubes to fit through the first 4 ribs. Then I installed my additional spar wiring molex bracket, ran all of the wiring in the left wing, and installed adel clamps in the area where the wiring runs along the spar.

The additional molex connector bracket is supporting the two additional molex connectors, one for the pitot heater, and one for spare wiring. The red and clear tubes are protruding from the enlarged 5/8th holes
At all stations on the main spar, I have an adel clamp like this one installed. These have slightly longer AN bolts, and right now they are not torqued. The clamp keeps the wires from moving, and protects them from chafing on the spar waffle plate edge

Wing systems

Today I started installing the wing systems. I ran some of the cables out to the wing stops, but then discovered I made one error on the routing and had to undo some work. Unfortunately I ended up snapping some molex crips, so I need to order some replacements from Vans to finish the wing tip lighting runs.

Fuel sender wired. I tested the connection, seems ok

The first, and incorrect, routing of these wires. These need to run along the spar one more bay before stepping aft (up). I fixed the issue

Wing systems hole enlarging

Tonight I used my step drill to up-size two sets of wing system holes in the left wing. one will carry the AOA and Pitot pneumatic lines, and the other will carry the addition wiring for the pitot heating unit.
