I have been running the rest of the wires that run aft from the dashboard and trying to secure that wire to prevent future problems. The aft seat headset jacks are soldered and secured. The front seat jack wires are run but I have to wait for the front console to be installed before I can install the jacks. It has been oddly satisfying clamping and lacing the wires together. I am almost ready so start crimping some pins and making the Dsub plugs in the dash area. I also received my SS flexible brakes lines from TS flightlines and got those installed right away. I personally think it was a good decision so that I dont have to worry about heat or sun melting or making the plastic tubing brittle over time. I am only putting the SS line in the gear legs up to the fuselage. Once inside the fuselage I will transfer over to the plastic tubing. Also my plan for the firewall forward is to make hard line that connects to a bulkhead connector and then I will once again transition to plastic tubing inside the aircraft. I was just worried about the heat and the plastic tubing degrading over time. Lastly I have been looking for a solution to bring fresh air from the NACA duct, and split it to go to the rear cabin and also the front dash. I was able to find a silicone 3" WYE adapter that transitions to 2" which is perfect for what I need. The biggest drawback is that its a little heavy so I may just trim it down.
