From my understanding the switch is what you have to shave if you are placing them on the left of the steering wheel. I couldn't tell you what you might have to do if you are placing them in one of the blanks in the center console. Could be wrong since I have actually used this switch myself but they seem like a good fit with minor tweaking.dylanc said:The website says "does not fit 03+" 4runner, but if you look below that in the reviews, someone mentions that it fits 03+ 4runner with minor shaving.
