Yeah, there is cutting required, you just have to cut a diode off the board, not hard at all. I told him because he was installing the flex fuel wires, that since he was already in there and had everything apart to go ahead and cut the diode to do the ISO mod.
Its very, very, very simple. Its easier to do that than it was to instal the E85 wires.
