The grommet is hard to reach, ill give you that. Just use a coat hanger, make a small loop, thread it through from the inside to the out, put the wire through the loop, and pull it in from the inside of the car as far as you can, from there, lie on the passenger side floor, and go at the grommet with a screw driver (a right angle driver is the best) to pull in the wire. This is how i did it. Its really a two man job, so just grab a buddy with a flashlight. Otherwise it will just take longer... good luck, if you have any more questions, just ask.
