I came up with a solution to that when i was wiring up my sable. you can't go through the stock tube on the drivers door because it is actually a plug. what you have to do is pull away the carpetting and kickpanel on the drivers side and drill a 1/4-3/8 inch hole in the door jam as close to where the factory tube comes out, then drill one on the door too. run your wire through the two holes, and cover it with split-loom tubing. seal the two ends in place with silicone sealant. and wrap electrical tape around the split loom. that is the only way i figured out to do it. you can't go through the factory tube on the driver side.
