I got started on this section by attaching the control cables on the firewall forward side:
Showplanes prop governor cable bracket attached in place
Prop governor cable attached to the governor through the bracket
Throttle cable reaching the throttle body underneath the engine
Throttle cable attached to the throttle body (incorrectly)
After attaching it with this hardware, I realized that not only was it in the wrong hole (the outer hole requires longer cable travel), but it was also hitting the arm itself when it moved, so I had to switch to the Vans-recommended hardare:

I then started routing and attaching the control cables inside the cabin, at first using the Aerosport-provided bracket:
Possible control cable routing over the tunnel to the quadrant
Original control cable bracket, as far down as it'd go
It turned out that that bracket didn't really fit - it was too short and couldn't easily be kept down against the top of the tunnel without significant preloading from the cable bend, so we had to make our own bracket.
Figuring out the exact angle, hole position, height, etc. took a lot of work - there's a lot of variables to consider, like the cable's bend against the tunnel top, clearance to the inside of center console, clearance to the fuel valve parts, room for running wires and the heat control cable, the maximum swivel angle of the cable tips, etc. Our first version was workable with almost all of those, except the holes were too high so the cable was hitting the inside edge of the console, and the angle was not sufficient, so the cables were hitting their maximum swivel:

so we made yet another bracket, with a larger angle and with the hole slightly lower, and match-drilled it into the tunnel top for attachment with AN3s:

Throttle and prop cables no longer interfering with the inside of the center console
I added nutplates to the tunnel cover, primed the bracket, and attached it:

With that done, I'll wait until I close up the tunnel to do final attachment of the cables (not a lot left until then either).
