Get on your back, and look northwest of the clutch. See where that yellow wire goes? Go there. It comes out in the engine bay as shown in the pics. You can also route it through that grommet from the engine bay side (I used a bicycle spoke b/c the end ius rounded and won't poke into things, but a carefully bent coathanger works too). In the pic, look down under the wiper motor - see where that red wire goes through?
And no, the red wire doesn't change to yellow, it's not a magic grommet.
From the pillar, stick the hoses/wires down 'tween the dash and the nearest other body panel, protecting them from abrasion somehow (a wrap of electrical tape works) and fish 'em out while on yer back with yer head under the dash...
