Continuing wiring and avionics

Tidied up the console wiring loom, installed adel clamps and cable tie mounts, wired the Garmin GSB15 on the center console back panel.

Installed 90 degree TNC connector for GTX45R and 90 degree BNC for GA56 antenna cables, then installed the GA56 GPS antenna on the firewall mount bracket. Ran RG400 cable from the GA56 back through the firewall towards the panel - this antenna will be used for the Garmin G5

Trimmed and fitted the pitot, AoA and static tubes to the GSU25C ADAHRS unit along with appropriate Y and T fittings required to route to the G5 and alternate static ports on the instrument panel

Adjusted and fitted PET protective covering and heat shrink on the RG400 antenna cables

Fabricated and installed a vertical support for the panel from the console floor tunnel to the shelf. Midwest Panel Builders recommends this given the weight of the shelf, I place mine in the center of the console rather than on the left edge as it is out of the way of the side console panels and provides an option to secure pipes and wiring

Fitted the fuse block for the alternator and VPX combination on the firewall strengthening channel on the pilot's side just below the shunt

Wired the EarthX battery fault connection, the shunt hi / low wires, alternator wiring including the resistor as specified by Midwest Panel Builders (to prevent erroneous alternator error messages on the G3X system), and some master contactor connections

Tidied up the ECU wiring, fitted the lan A and B connectors to the fusebox on the firewall including O-rings in the CPC connectors and EMS backup and the RE1 X3 connector
