Some possible places to run the wire:
1. I can't tell what this line goes into, but it might work.
2. If that is your vacuum line, I am assuming it is going into the cabin, so you could just run it with the tube.
3. Do those wires run into the fender well? If so, you can run them to the open area where the door hinge is and then under the door threshold bumper.
1. Same as #3 above, may be able to run through the fender well.
2. Could use the main wire harness grommet, but I would try the other options first.
3. That looks like a perfectly usable grommet. I'm guessing it goes straight into the cabin right around the back of the stereo area.
