I've just hung the engine and am now confronting all the items that must pass through the firewall to operate it.
Concept #1. It seems to me that there are 5 categories: mechanical cables, Fuel, Cabin heated air, electrical power cables, and sensor cables.
The fuel and heated air pass-throughs are already in the firewall.
I understand that laying power lines next to sensor lines is not good, so that would seem to indicate at least 2 more openings.
Finally the mechanical cables. There are 3 already there conveniently lined up with the throttle/mixture/prop quadrant, so that would leave 3 more cables for cabin heat, oil cooler shutter and alternate air. Since the wisdom of Van's gave each cable its own opening, should I continue that and give each cable its own, or can they be grouped?
Is the pass-through fitting the same for mechanical cables as it is for wiring?
On the other hand, Concept #2 might group items by location, and so mix wiring (but not power and sensor) with mechanical cables if they're going in the same place.
Thoughts?
