Wiring harness measuring, spark plug harness complete, subpanel fuse box install | 2.10.2021

Finished up the fabrication and install work on the spark plug harness for the SDS. Below is the best routing that I could come up with that didn't interfere with the engine cooling plenum or anything else. Everything is neatly ziptied and awaiting the install of the coil pack (waiting on new magneto studs).

New cables in red.

As I was finishing that up, Emily's dad Steve showed up to help me measure for the wiring harness. We started out by placing all the remote mount instruments in place on the sub-panel and making sure everything fit.

We were going to measure from everything to everything else, but we realized that we could remove both the panel and subpanel from the plane and mock it up on the avionics table just as it sits in the plane, so we really only needed to measure anything *not* on the panel or sub-panel, which made things much easier.

Here's Steve writing up the lengths.

Once we were done measuring, I cut holes in the sub-panel to mount the fuse boxes. These will be accessible from the co-pilot's footwell if needed.

Fuse boxes installed.

 I also terminated and attached the magneto wire to the right mag.

That's it for now!
