Cut a larger hole in the top cowl for the zaon. Built and riveted a tray for it to set on. Fabricated a cover to fit over the zaon and attach to the cowl. Drilled a hole in the cowl for the xm antenna. Drilled a hole with a slot for the gps antenna. The antenna will cover the larger hole and the slot allows the cable to go through the cowl. Fit the forward interior panels. Had to make several revisions for the wire harness and vent ducts. Ran a wire for the radio fan from the avionics buss through a 1.5 amp fuse. Installed a connector on the wires and the fan. Pulled the zaon wires back from the bulkhead and re wired to the new location.
