i ran mine through an existing grommet that had four wires running through it... works great. 
try and find a hole that has been pre drilled either from factory, or maby for an aftermarker allarm. thats how i ran mine, just pulled the other wires out of the way enough to run the vac line through. :icon_bigg
DON'T DRILL!!! Holes should be there already with a rubber plug or existing grommet! Sharp holes and fresh wire don't mix!
right by the clutch pedel is a empty hole, if you look in the engen bay to the lower left of the clutch master cylender their is a pyle of sylacone, and a small hole in the midl of it, that goes all the way into the cab right by the clutch pedle
