It's quite easy to work out the UV coordinates from a tempate or texture map.

Open it in a graphics program, and make a note of the size of the image in pixels.
Pick the spot  you want to know the coordinates of and note the number of pixels it is from the bottom lefthand corner (the origin).
Divide the number of pixels right of the origin by the total number of pixels horizontally to get the U coordinate.
Divide the number of pixels up from the origin by the total number of pixels vertically to get the V coordinate.
