Two firewall wiring pass-thru plates were fabricated from 1/8" titanium plate. A ledge was milled into each piece so that they have some overlap where they meet in the center. There are 3 holes, two for the large Rotax engine harness HIC cables, and one for other sensor wires and the alternator cable that pass through the firewall. Silicone grommets were used to seal around the cables, and the high temp sealant (Permatex 27036) was also used to seal around the titanium pieces.

Our EarthX lithium battery has two vent ports that need to be connected to hoses that can exhaust fumes outside the cabin. This provides a path for unwanted gases in the unlikely event of a battery failure. A vent outlet was installed on the bottom of the fuselage. Teflon tubing will be used to make the connections. Per the manufacturer, nylon fittings can be used if more than 2' from the battery, and brass fittings are needed for closer connections.

We also ran one additional wire from the battery to the front to accommodate a line from the EarthX lithium battery that provides an indication of a battery fault.
Additional work is being done to organize, bundle, and clean-up the wiring. Still quite a bit of work to go here, but we are making progress.

Rerouting of a coolant hose was completed to provide more clearance, and Adel clamps were also installed to help hold it in place at the Rotax ring mount. Still need to attach some fire-sleeve material at locations near the exhaust, but at least the routing is completed.
