Still roughing in the electrical system I mounted the Master Relay, the Starter Solenoid and the Shunt onto the Relay Panel that I had already installed in the bow area by the Battery and connected some of the heavier wires. Next task was to wire up the headsets' and microphones' jacks for the Pilot and Co-pilot. The wiring diagram & list that came with the Harness is pretty clear on how to do this, if you are experienced... but I am not, so I spent some time watching YouTube videos until I figured out the details of what had to be done. The complications involve the shielding on some of the wires involved and understanding what the 'tip', the 'ring' and the 'barrel' of the jacks are. With the wiring done I then bolted the two Jack Plates back onto the Root Support Mid.
