I ran the two endurance buss wires from the VP-200 CUs to the master solenoid and added them to the connection there. I also made the primary connection from the master (at the firewall penetration) to the power input of the two CUs. Then I spent some time making the solenoid harnesses. In the first image, you can see the master solenoid harness consisting of a jumper from the input side to the first activator pin and a diode to the second activator pin. I also made up a diode wire for the ground-power receptacle to its solenoid (second image) and reinstalled the receptacle. Notice the fuse bodies for the two endurance buss wires, and a fuse body for the ground wire from the ground-power contactor. That cleco is just a temporary ground; I will add a dedicated airframe connection before I close things up. All I'm missing now are the OVM for the ground power solenoid and the wires from the VP CUs to the master solenoid (waiting on wire and a missing connector body).
