If you want to install only the panel, without the internal views, and leave the default virtual cockpit as it is, follow these instructions. Unzip the the zip file to a temporary folder. Copy the Kingair_Radio20.gau from the Gauges folder, to the FS2004 Gauges folder. Re-name, or copy your default or current panel.cfg file to another location for safe keeping. Then copy the panel.cfg file in this folder to your aircraft's panel folder (overwriting as necessary, after backing up your original panel.cfg). Copy these bitmap files from the "Panel.dc3mdpnl" folder to your aircraft's panel folder : SWpnl-1e2.bmp tag.bmp
