Ran Oil Cooler Valve and Alt Air Cables

I drilled two additional holes in the firewall for the eyeball pass-throughs.  The top hole is for the cable that will control the oil cooler butterfly valve.  The lower hole is for the cable that will open the alt air port.

It’s pretty much a straight shot from the upper hole to the arm that will operate the butterfly valve (especially after I adjust the angle of the eyeball).  I’m a little disappointed in these butterfly valve though.  Aircraft Spruce specified this hole size for these cables, but the holes are a little oversized (they should be a few thousandths undersized so they securely clamp the cable).  I’ll have to wrap some aluminum tape around the cable to tighten up the fit.

The lower cable will route behind the spark plug wires and be clamped to the oil return fittings.

On the other side of the firewall, it’s pretty much a straight shot from the panel to these holes.  They’ll be anchored to the bottom of the subpanel and tied together in the middle.  It looks like they’re about to touch the rudder pedal bars, but there will be roughly 1″ of clearance once everything is anchored.
