Remove the kick panel under the glove box, it's three plastic push pins. Then pull back the passenger foot carpet. There is a large square grommet around a wire harness you can remove to run a thick wire, or to the left of that is the round grommet for the cruise control cable.
Use a razor to notch out the square grommet to accompany the wire if it's too big, it's designed to be taken out and put back in. Or just use a stiff wire to poke through the small grommet but be careful not to accidentally push out the cruise control grommet because it's a ***** to get back in.
