Did you at least do the driver side? Based on above post the drivers side switch cluster has both required wires. The passenger side shouldn't be that difficult if the wires aren't there to begin with. You should be able to fish a wire through the door harness boot using a snake. Worst case you can use a coat hanger straightened out but I suggest you smooth out sharp end with sand paper or Dremel tool so the coat hanger doesn't pierce any other wire jackets. I actually prefer to use fiberglass snake rods.I tried to light up my door switches, wrapping the led lights is not a problem, the problem is powering the led's, I thought I could run a lead from the widow switch thru the door pillar,thru the wiring harness and in. NO WAY, I would have to drill a small thru the door pillar to feed a wire thru and than to power. Not as easy as I thought it would be. I think TOYOTA ENGINEERS failed on this one.
