Wiper speed upgrade from 2 speed (hi and low) to 3 speed (intermittent, hi, and low)

[rakenronn]

Just installed a new column switch for my 1992 Mitsubishi L200. Stock only has 2 speeds (hi and low) and the new one has 3 speeds (intermittent, hi, and low). All switches work except the intermittent switch. Any ideas what to do? Thanks. http://www.mightyram50.net/vbulletin/attachment.php?attachmentid=26377&stc=1:))
