Turn signal flasher

[Tom-MI]

This may seem elementary but I need some help. I am making up some turn signals. All seemed to be going good until I got to the flasher. It is a three prong flasher. There is a "P" at the 12 o'clock position. A "L" at the 3 o'clock position and a "X" at the 9 o'clock position, What wire is suppose to go to each letter. There are no clues on the can.. I tried a picture but the markings are too faint to read.

Thanks
