I tried a welding wire with a loop on the end from the top again and beleive that I am getting far enough but the end appears to be exiting into the space between the inner and outer cowl rather than into the interior cab space.
I recall having that issue. I think if you stick your pull wire up from the bottom and then tie the dome lamp wire on to it and pull it down thru the pillar, you'll have better luck.
Here's another photo of that area (minus the cobwebs.
)
