John, so there are 2 types of those type of furd solenoids? & what is the ISO relay? EDIT I think I got it, one is a regular 4 terminal relay & the other is the furd type with the 2 small terminals labeled S and I. I think a momentary contact switch sending fire to the S terminal & you're good (if the metal base is grounded). Not sure what setup you have with the NSS
