My Dynon Skyview and Garmin SL40 wiring. The last photo shows my tilt-down panel that rotates down 90 degrees for servicing the backside. By leaving long enough service loops in the wiring it allows the panel (when bottom 4 screws are removed) to tilt down without disconnecting any wires. This system does not require removing the boot cowl to have full access to the instrument bay and its wiring.
