Where is the light switch on a 42 GPW?

[Lynn Eades]

Go to the G503 forum, and read without stopping for about a month.
If you want to know more after that (and you will) then keep reading. There is a lot there. WWII Jeeps have been done, inside out, and back to front, a bit like a nose, most people have one, so the G503 is probably the most detailed M.V. site there is.
As far as your light switch goes, Is you dash panel original? Your light switch should be the most left switch on your panel. cheers.
