The last engine control cable to be positioned was the Bowden cable for alternate inlet air. This simple pull cable starts in the cabin with the business eng going to a rotating door that opens a hole in the side of the inlet snorkel so that the engine can still breath if the normal filtered air source in the cowl inlet is blocked. Because the alternate air source is hot and unfiltered, it's not meant to be used except in case of emergency. But, in an emergency, you want to be able to find that knob in a hurry. I thought about this quite a bit and decided that for that reason, it made sense to locate it next too the throttle. In the first picture below you can see the 5 (!) knobs on the throttle quadrant sub-panel. From left to right, they are: Alt air - Throttle - Prop - Mixture - Oil cooler airflow. From that face plate, all 5 of the cables are affixed to the sub-panel via adel clamps per print, then make their way through the firewall in appropriate locations. For the alt air, I brought the cable left, then up to secure to the fwd deck rib so that it wouldn't be just flopping around, then out through the firewall on the left side above the rudder bars. Once I get the snorkel in place, I plan to bring it straight fwd just below the rocker covers to where it will attach to the door. This is something I've been meaning to get to for a while and just one of a thousand small tasks that still needs to be wrapped up. From a psychological standpoint, it's very gratifying to knock out a small job every once in a while where you can really see immediate success.
