I am trying to install a backup light on my 93 Kawasaki KLF 400 Bayou 4x4. I want it to come on when I put it in reverse but can't get the wiring right. Any help? <IMG SRC="smilies/glasses.gif" border="0">

if there is an indicator light for reverse on the handlebar, use that to trip a relay that is powered from the battery.
