Trying to load pics I took for you but its not working.
There's a black rubber "tube" going from the door to the cab. You need to take both ends out and run the wires through that. The end going into the door is easy, you can pry it out with a flat head. The end going into the cab takes more care because its held in by clips that break easily, especially if its cold out. Also be careful not to pinch any existing wires.
I would try and run a wire hanger or something of that nature through it first, then tape the ends of the wires to it and pull it through, well help out a lot.
EDIT: You're also gonna have to pull the kick panel off to get the wires through.
