I did not take off the lower tupperware, I took out the floorbroards and the rear(passenger) foot pegs, the whole thing(silver) is just held on there with 2 bolts, but there are tight. I was then able to reach my hand up there and route all the wireing. However I did note that in the oweners man. there is istrurctions on how to remove the tupperware you are wanting to remove, its to get to the service parts, like the oil filter.
