Today I worked on installing the big wires in the engine compartment. They are the 2 AWG main engine ground, starter, positive battery and the main engine ground. I also installed the ground braided wire to the main wiring ground plane. Nothing unusual, but the big wires are stiff and require support with Adel clamps along their routes. Make sure all on the terminals have solid contact, I used internal star lock washers on the firewall and the engine.
