What I do is dislodge the connector from the a-pillar (from the door jamb area). Use a large angled pick/hook tool, something like you would use to free a stuck radiator hose. DO NOT remove the rubber boot from this connector, as you will probably not get it back on. Once you get that connector free from the jamb, pull it out some, and you'll see that you can actually "split" the connector again. One half will pull back into the jamb; the other half will stay w/ the rubber boot. Then you can feed your wire from through your door, through the boot, and through the connector- NO need to drill another hole into the connector. Then feed the wire through the kick panel area, which is a whole 'nother pain in the ass again on the driver side (remove the amp, makes it easier). Once you have your wire through, pop that connector back into the jamb. You won't be able to reconnect the other half, but it doesn't matter. The connector still clips into the jamb just fine. I've been doing this for years (wiring up Muth signal mirrors) and works like a charm every time. Still takes me about 2.5 hours to get wires through both jambs though.
