i just read this thread http://www.cb7tuner.com/vbb/showthre...threadid=13494
and was wondering if anybody here has any experience w/ this, b/c the instructions are a little vague as to what to do w/ the razor blade. i'm really considering this DIY b/c my new HU has a blue backlight. also, i didn't put this in the DIY section b/c of low traffic there.
