I mounted one in my pickup in the floorboard, It was just under my right leg close to the seat riser. Had to pick the location so it wouldn't interfere with the frame cross member. I am a big guy, in the middle, so was harder to get to than I expected.

I have also seen them mounted in the front of the seat riser, both on the left and center. You will have to make something to keep the things stored under the seat from getting to the switch lugs.

Great safety add to your A. Had a short in the starter switch that got pretty hot and smoky. as simple turn of the switch and the short was over. Easier to fix when everything is dead
