I usually install programs/utilities to their default path. This makes it much easier to locate them & install updates. The default path in this case is C:\Program Files\CfgEdit
CfgEdit is an excellent program although not fully compatible with FS2002. The preferences will need setting correctly to work with it. See my reply to your query, now moved to the Scenery Design forum. You will need a basic knowledge of panel design to use it properly.
The "radar" gauge I tried works well & comes with instructions for adding it to any panel manually in Notepad. This is usually a simple matter of Copy/Pasting the new entries into Panel.cfg & modifying them accordingly.
PS. The one I tried is AIMap. It worked well for me although some people report problems. There are alternatives posted here.
http://hacksaws.fsgateway.com/fs2002_utilities.htmIt's possible these are also posted in the SimV Gauges section.
PPS. Install instructions for AIMap copied from the Readme. It's a proper gauge & does NOT need FSUIPC.
INSTALLATION
Copy aimap.gau into the GAUGES directory where flight simulator is located.
Just add it in a panel you desire (737, Cessna), by editing the related
PANEL.CFG and adding a new Window as follow:
[Window Titles]
window00=Main Panel
window01=Radio Stack
Window02=GPS
window03=Throttle Quadrant
window04=Overhead Panel
window05=AIMap -< new line added
and after last window, in this case [Window04]:
[Window05]
size_mm=280,350
position=4
BACKGROUND_COLOR=255,255,16
VISIBLE=1
ident=AIMap
gauge00=aimap!ai_map, 0, 0,280,350
Pay attention to assign the correct number to the window you just added.
