ACM Wiring (2)

I wasn't going to do much more on the wiring, but I also don't want to just twiddle my thumbs while I wait for Van's to ship me the firewall forward stuff.  I decided to clean up the subpanel wiring as much as I reasonably can at this point.  There are still a few wires to run that go in the "Aircraft Front" connector, but most of those come from areas that will route via future holes in the subpanel.  I bundled the left and right side wires and clamped them in place to send them behind the subpanel.  At some point when I'm extra sure there's no more wiring to add, I will make all of the bundles prettier and add a bunch more zip ties.  Most of the connections on the ACM that are still empty are for panel devices.

I have learned a few lessons for the next plane (which I'm sure I'll forget by the time I ever build again).  I should have given myself just a little bit more wire length and then put the service loops in before cutting the final lengths and crimping pins on.  I measured as best as I could when I did my initial wire runs throughout the airframe, and even though I gave myself a buffer, it was too close for comfort on some of the wires.  As is, I have some wires that were barely long enough to reach the ACM, and others that were long enough to give a decent service loop.  In the end it all works.  It just looks a little haphazard behind the scenes since there are varying size loops, no loops, etc.


Even though I don't have the Van's FWF parts, I did receive my exhaust from Vetterman in South Dakota.  He does really nice work.
