Running wires from door panel to inside car

I spent like an hour trying to solve this problem on a 2000 Honda Civic last week.   I needed to run 4 wires from the driver door panel into the driver side kick panel area.  The only hole on the drivers door panel was a square and was occupied by the factory wiring connector.   Couldn't get a drill in there to add another hole,  so ended up disconnecting the factory wiring connector and forunately the center area of this multipin connector was not occupied with wiring so I drilled a whole there on both the male & female connector.   This worked fortunately,  but just wondering if there's an easier way when I come across the type of problem on other cars.

Hi Thinkster, that's the way do it. Just make sure you also run your wires through the existing loom/sheathing if any exist, if none exist, add it.
