Soon after buying my '06 with power driver's seat my wife said she wanted a power seat also. I bought the seat track with motors and controls from Caldwell Dodge online and installed it. I bought the wiring harness connector from the local dealer and installed it. For me the toughest part was cutting the hole in the leather for the switch panel. I was afraid of making a permanent mistake. I did have to fabricate a mounting box for the switch from sheet metal. Total cost was just over $400 if I recall. You can't tell itfrom a factory install.
