will be using twin fans that is 100%, now the switch i am not sure (don't want to use then in hose probe things)
here is a switch that i have found to be ok and a wiring diagram that i thing would work well
also the switch, where would it go? i am thinking doing an hose pipe that will have mounting for the sensor, would it go top hose or bottom (considering that our system is upside down)
any feedback guys:

the sensor of choice is SAAB 9000 unit (original comes with two earths) the unit is simple and easily accessible after market. plus to me has a good temp range.
