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 holesAt 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
