the high idle mod activates the PTO circuit in the "customer access" wiring group under the dash. im not sure that the X has it or not, not being something typically using the PTO function, but if the wires are there, then I dont see why it wouldnt work
This mod is different than the computer's high idle, the mod puts the rpm's to roughly 1200. The computer will adjust on an as needed basis for cold warm ups. The link above also has a link in it somewhere that shows how to get the engine vitals to show in the odometer display and be able to cycle thru them
