Tachometer Plug Solution???

Hmm… I am not going to be old-fashioned about all this I hope; I know that there are many ways to skin a cat! This solution will most definitely keep dust and shit out of your tachometer gear, but this pictures deserves to be on http://thereifixedit.failblog.org/

This tachometer plug is more fun and practical, than cool and aesthetic…
Or am I just getting old and grumpy???
