Just follow the pedal up under the dash. You have to lay on your back to see it. The nut that holds it on is a 17mm and you will have to use a open end wrench. I just adjusted mine in my Del Sol because I was having to push the pedal in to far to get it to start. The switch dosen't make until you push the pedal in. From there, the Honda book says to screw it in until it touches the pedal arm and then turn in 1/4 to 1/2 a turn. I just adjusted by trial and error. Just adjust the switch where you can get the car to start with a normal leg extension. You can see the electrical plug and nut, but you have to push the pedal in to see the part of the switch that makes contact with the pedal arm.
Good Luck
