Why would you want your IC pump on a switch in the first place? IMO it should be running all the time in the first place. No point in having an IC if you ain't gonna use it. If you're worried about pumps failing, just get a good pump in the first place (like a GM) and have many years of trouble free use (I have over 70,000 miles on my original IC pump and 3 years). Just my honest opinon.....
