I installed three blast tubes. One is plugged into the fuel pump cooling shroud. The other two are pointed to the L/R magneto. I made a T bracket that connects to a cushion clamp to hold the magneto tubes in place. Next, I wired the seven terminals on the B&C backup regulator. I really like its final location, which is out of the way, yet easy to remove if needed. Three of the wires from the regulator are connected to P1, so I routed those to the front co-pilot side. The rest of the day I spent on the center counsel. This unit will house all the headset connections but will be removable during the annual inspection.
