Started building wires and running them on the firewall components. Determined and cut wire lengths and crimped the appropriate connectors on the cable ends. Using black heat shrink tubing on the ends of ground wires. Started using red heat shrink tubing on the ends of the power wires, but will go back and remove the red heat shrink tubing and replace it with black. I will then place a small wrap of red silicon "rescue tape" on the ends of power wires. I'm doing this because I can't seem to find red heat shrink tubing of the same aircraft quality as is available in the black. I don't want to use standard automotive or lower quality quality heat shrink tubing in the engine compartment.
Most grounds are going to the two-sided firewall "field of grounds" frame ground block. Grounded the engine block to the frame ground with 4 awg wire.
Printed 6-point text labels and afixed to the wires on each end with clear heat shrink tubing.
Installed the fire sleeve on the bulkhead penetration mount to make running the firewall to cabin wires possible for now.
Crimping a large gauge battery terminal on a battery wire.
The firewall penetration fitting to safely bring wires through the firewall from the cabin.
The start of the main power distribution wiring using the Vertical Power PPS solid-state power system.
