Just had a set installed at the dealer for $300 on my 17 Highlander today. Decided to have dealer do the work since my car is still under warranty and I feel uneasy about doing work on a new car. I can do the wiring part since I have installed rear view camera, but not sure how to remove the seat cover to install pads. Anyone has DIY on how to install heated seat on gen 3 Prius? Thanks!
